Hey Everybody! Haven't been posting for a while thanks to exams, but I'm back! Anyway, can you great people post some suggestions of your favorite quest/adventure mods? I'm finally sick of the vanilla quests and I'm craving something new. Thanks!   

Well the biggest mod I would recommend to make New vegas bigger is Tale of Two Wastelands, but that requires you to own Fallout 3 as well.
Other than that I recommend

The new Vegas bounties series
boulder city
Project Brazil (Only new games)

I also loved Inheritance, Strangers Abroad, D.E.I.M.O.S.
The Collector is small but nice, almost vanilla.
The Most Dangerous Game is very peculiar and I find it technically very well done, something different from common. If you want some actions, Psyclones of Mystro, I love it as all the other works from him, a pure professional and impeccable bloodbath.

@LaEspada do you mean the facelift projects by Talon Company?

@A.J. Thanks, man. Haven't talked to you in a while! Trying out D.E.I.M.O.S. first, then Strangers Abroad. Gonna DL the rest soon.

Thanks for the suggestions, guys. Keep 'em coming!

Lawless Vegas , A trip to the Bank , Afterschool Special and Misterious House are the ones i'm using now

New Vegas Bounties 1 and 2 are the obvious suggestions, considering they're the most popular quest mods ever, and New Vegas Bounties 3 is in development to round out the trilogy.

If you don't mind a quest mod intermixed with a new companion, Russell, by the same author, is of the same standard of quality. Inheritance, as mentioned, is also by SomeGuy, and fantastic.

Willow is also a popular companion mod that contains a few quests, but if you don't like Willow as a character I'd suggest bowing out of that one, as they all mostly revolve around her and her relationship with you.

Beyond Boulder Dome is very impressive in adding a new worldspace, creatures, weapons, armors, and a main questline, but the questline itself can be somewhat confusing and isn't the highlight of the mod.

Saxxon's Quest Collection adds a -bunch- of small little side quests spread throughout the wasteland, and is very nice for a new playthrough if you're looking for somtehing to do.

And, finally, if you're a Whovian, Fallout Who Vegas was recently updated with an impressive array of features into Fallout Who Vegas 2, featuring a new worldspace, Time Lord Regeneration, new monsters to fight, and of course, an in-depth TARDIS simulator along with a new companion.

I'm having a lot of fun right now with the NCR quest mod. You basically join the NCR and rank up through the levels.

theengineeringguild.co.uk/node/37

"The NCR Mod allows those who Embraced the NCR to join them officially and even sign up for the NCR military.

You start by saving Primm and handing it to the NCR for protection, that is how you earn your NCR Citizen ship and your life in the NCR begins.
Or you earn the respect of the NCR and find alternative way to join, the choice is yours.

During your time with the NCR you will find your self subject to its laws, should you harm the NCR you will find your self outcast and stripped of your ranks and citizenship papers. If that happens you will have to earn their trust again to get back in. But should you help the NCR, you will find the NCR opening doors for you that you never new existed.

As an NCR Citizen and then join the NCR Army. As your skills grow, you will find new options unfold before you such as the ability to join other units and wear other uniforms or use other equipment. Accept training or do the missions for the the unit you join. Everything from simple patrols to all out battles are available here depending on the unit your in. To top it all off you get bonus perks awarded for training, for long service with your chosen unit and other things.

Every mission you take counts towards your NCR Rank and you can rise all the way up to General in this mod. Also every mission you take for a single unit, counts towards your veteran badge for that unit and Veteran Badges will unlock new material in the future for those who have them."

Besides previous mods, try these:
1. The Couriers Cash
2. The Rockwell Pursuit
3. Denver Dog City
4. Badlands
5. Project Genesis
6. The City
By the way, A Quest For Heaven 1/2/3 are also very cool mods, but as I know, there are only Fallout 3 versions on nexus. On our russian site modgames.net there are versions for NV, but they are all in russian(((

Deimos http://www.nexusmods.com/newvegas/mods/43411/? is pretty good. It is from the maker of Project Genesis for Fallout 3 and Falskaar for Skyrim Alexander J Velicky.
If your in the mood for a lot of combat, and I do mean a lot of combat, try Area 51 http://www.nexusmods.com/newvegas/mods/42486/? . I don't want to spoil anything, but the final boss fight is very impressive. It also comes with a very unique looking player home and some unique weapons.

Project Brazill is a very good quest mod and the NV bounties is a good one too.

No mention of the New Bison Steve? Really? I feel its better than Afterschool Special, even if it is in a similar vein. Personally, Afterschool Special throws off the beginning of the game too much, just like A World of Pain. I would also second Saxxon's Quest collection. Diemos is rather well made, though I personally didn't like it as I don't like rolling solo. The Rockwell series I haven't tried as the many, many reports of bugs and issues from the comment section makes me mod shy.

I always use Somegu2000's quest mods which are all really great and lore friendly, but I also use Saxxon's Quest Collection which adds around 20 new quest all fully voiced and 2 fully voiced and lip synced followers!

All of the Someguy2000 mods are super high quality and fit into the base game very well.
If you're interested in something bigger, you should definitely check out Project Brazil as well. It's basically a whole new game.

like mentioned before, the someguy series are incredibly high quality.

also ,if you want more adult content, Coito ergo sum is a great mod too

Like Zetman said DEIMOS is a great quest mod. It adds a few hours to the game and has a cool time travel paradox. It had great voice acting and sequences.

New Vegas Killer by SomeGuy2000 or Beyond the Boulder Dome by BBDT they are pretty well made and elaborate. SomeGuy2000 really outdid himself with New Vegas Killer, it's funny, simple, yet entertaining non the less. Beyond the Boulder Dome is a damn fine example of modding gone right. It's so good it could have been a DLC in my honest opinion.

Thank you all for the excellent suggestions. My NV is now littered with quest mods.

Feel free to suggest other quest mods here, but I'm quite satisfied.

D.E.I.M.O.S. is a very awesome mod so is after school special umm im sure nipton rebuilt will be if it stops crashing my damn game i hope that gets fixed soon.

Lawless Vegas is my personal favourite, that mod was surprisingly well-made and well-scripted. The endorsement was strangely low for some reason though

Deserter's Fortress by dree74 is a gem of a quest mod and definitely worth your time and a recent mod that can classify as a quest mod would be Nipton Rebuilt by Jokerine (although I have been hearing some things about it being buggy and glitched). But you can't do these mods without a proper companion to join you aren't I right? YOU NEED this guy, and by this guy I mean Bad Mothafucka by Someguy2000. He's simple and get's the job done lol.
