Maybe there's something in the Indie community for you [1]. We've got different tastes, obviously, both in requirements for a game and music (;-p), but as someone that didn't like the Doom series all that much I think there are ~close enough~ similar games out there. The one I listed (Disclaimer: Own it, like the theme, hate the sounds and the Doom-like 'what you kill is eventually going to respawn') might be refreshing for a while.
