I know a lot of players get bored with the standard assets of the games, but I am not one of them. As long as the modder knows how to use them wisely, them I am a happy headcrab.
Given the choice I much prefer a mod team spend the time on making more maps and therefore more gameplay for me. Of course, the usual It Depends rings loudly in the air, but these polls are just for a little fun and we must assume that the quality of the new content is the same as the new maps.
New content is nice but I honestly don’t notice too many textures and the new weapons rarely make enough difference to worry me.
All in all, more maps please to extend my gaming.
