It's really smooth, top high detailed. I just don't agree it provide some new game play or something. I mean yeah it provide but it will play pretty much same as old GW 1.:) Though for old limited doom deathmatch maps, this is pretty damn good wad. I don't care about the 3D Floors but i appreciate the maps are made good with feeling and really great sized, which is pretty good. The era when people made maps where you discovered everything on map in 1.5 minute is i hope gone. :)
