Doom

The Good
At the time, the opportunity to waste crowds of zombies with a pump-action shotgun, whilst gliding through an attractively-detailed, texture-mapped setting was the selling-point (although nobody actually bought the game - everybody sat up all night downloading all 14 mb of it, instead). In retrospect the ability to play against three other people on a TCP/IP network was enormously good fun, too, and a portent of things to come. Nowadays it's still good fun for half an hour or so - with the recent 'GLDoom' 3D upgrade it has a whole new lease of life.

The Bad
Well, it gets a bit monotonous after a while - you run around shooting things - and after all these years it's too familiar to be really exciting. Still, it's almost beyond criticism.

The Bottom Line
It's Doom - you know, Doom. You must have heard of it. It's Doom. Doom.
