I still enjoy roguelikes and muds over todays offerings.
I like turn based strategy. Very few of those ever come out. Those that do fail me because of the failure to implement a decent multiplayer component.
Although I do play the odd FPS to get out some of the "gamer" in me
Playing Biochock at the moment and greatly enjoying that.
But for the most part games today fail me because of lack of options, lack of depth and lack of immersion. Maybe that is why I like games like roguelikes, muds etc.. The less graphics there are the more I am sucked into the game by my own imagination. It is rare that a graphically rich game like Bioshock comes along that actually grips me. (but I can only play that late at night as I have two young sons).
Some games I would probably love if instead of RTS they were TBS.
As a fan of play by mail games back in the day, and recently PBEM I know I am a not the target demographic, so it is up to me to find indy devs that enjoy the same kind of things in games that I do.
