I've been playing fallout for like couple decades now and I found out you guys have this mod page and stuff, I started playing Fallout 3 and then New Vegas and then I did one and two before the release of Fallout 4, I also checked out 76 after wastelanders came out, I've become pretty good at debugging and Frankenstein'ing mods to stay under the plugin caps, my most recent experience was running into the ba2 limit, which I wasn't aware was the thing, but it prevents the game from launching into the start menu, pushing everything into loose files until you get your ba2s under control helps this.
I also like cats, but the cats in Fallout 4 are pretty plastic, and perhaps a cat behavior patch would be a fun project.
