A valiant effort, doesn't quite cut it
This is about as good as graphics get on Super Nintendo. Also, it's Doom. There's nothing I can tell you about this game that hasn't already been said. It's arguably the greatest PC game ever made ported onto your SNES, and there's nothing wrong with that in theory.
The execution is a different story. Doom, as it is, surpasses the Super Nintendo's capabilities, which means sacrifices were made in porting to a 16-bit system. Textural detail is lackluster, and a lot of lighting effects were nixed in an effort to smooth out the gameplay.
Unfortunately, it didn't really work. Playing the SNES port is like dragging your feet through the mud. When onscreen combat gets a little hectic, the frame rate drops and controller response becomes alarmingly slow. To top it off, only 2/3rds of the screen is used, framed in a black box that is quite noticeable.
Because of limited sound functionality, ambiance and sound effects overlap and cut each other off. The simplified MIDI soundtrack stutters and somehow sounds offbeat the entire time.
The Bottom Line
Midway made an admirable attempt to port this PC gaming classic to the Super Nintendo, and largely succeeded. The sacrifices made highlight the inherent problem that this game was, and always will be, best on PC. Playing the SNES cart only made me crave the PC original that much more.
