The prefabs and standard.wad are from 1998 I believe. Due to this age they represent a remarkable antiquity value and we hesitate to give them up. In fact, it would almost break our hearts.
i guess this explains: -the interface -the default models -the default textures -the default sounds
lol... -wmiles and whistles-
I'd really vote for an updated standard.wad, along with some updated models.
