I play other mods too, and see things I like that DLV lacks, but then they get boring. It's usually a case of feeling like I'm playing vanilla after a while, when I try other mods.
I would like to see a load of things changed... the map... some of the factions... some of the artwork... but the game itself is amazing.
So many ideas that are so good they make other mods seem flat and boring.
DLV had given me hundreds of hours of awesome gameplay before I began work on it. Since starting to mod it I've played for thousands and it's still great, I still miss it when I play other mods. But modding for it has taken some of the fun out of it. I really like to explore new units and tactics, and of course designing that side of things ruins any exploration. I don't usually fall for all the traps I've set
