> Doom - the same - the feeling of nicely timed double shotgun shot is very rewarding, it doesn't matter you are shooting to rectangles. I always like how people bring up Doom as opposed to, say, Wolfenstein or one of the other 3D shooters of the time. What made Doom feel different with the controls was two subtle things: head bob and acceleration. In the same vein, there were other side-scrollers that featured characters jumping around. The side-scrollers that added acceleration physics (Mario, Metroid) were the really popular ones. I am trying to consider Castlevania as an exception to my acceleration theory, particularly the limited jumping movement in Castlevania 1 (similar to 8 Eyes, which allowed you to have neat two-player coop action but somehow was not as popular).
