I love Doom but I'm also bored of Doom

[Athel]

Maybe Doom is finally wearing out its "flair" for being fun...maybe Doomers everywhere will realize how boring it is to just shoot slow, predictable enemies down corridors with an OP weapon...maybe the ZDoom forums and Doomworld forums will die off...maybe...maybe we'll all start loving...C...C...Call of Duty?! *gasp*!

*ahem* Well, it IS a 1993 game...

How about a different 90's shooter to tide you over? They tend to be somewhat similar due to technical limitations at the time but, at the same time, they have very distinct themes and overall feel like Duke 3D, Quake, or Blood.
