I'm just starting to build my first PC. It's going to take a while since I know jack about hardware, and I want to make sure I don't buy the wrong things. When it's finished I've had this desire for ages of to a good HOTAS joystick and play an updated version of Freespace II. I've played a couple of space fight/trade sims and love the basic genre, but so much of the time it comes down to one of three missions: Go to X and blow up some ships; escort/take Y to X (and inevitably have to blow up some ships); go and mine/get Z, take it to X (possibly have to blow up some ships). It seems like there would have been more games which found more variety in gameplay styles, because, you know, it's SPACE. There's been some promising developments recently, so hopefully the space sim genre is coming back.

Some kind of team based spy/infiltration game, where different characters have different goals. Most multiplayer games I've seen/played (which admittedly isn't many) everyone is essentially in the same part of the map, doing the same thing. You might get different classes, but everyone is still very similar to each other (perfect example is Borderlands).

A game where hacking is not an unrelated mini-game (like the pipes game in Bioshock), but actually requires learning and typing in code, time constraints, problem solving, etc.
Similarly an RPG/magic game where the spells have to be written into a text field. This would work similar(ish) to a coding language, which makes the possibilities of spell results being more open ended, and you could have different syntaxes for different schools of magic, etc. I've seen Magicka and it's very similar to what I thought , so I'll be checking that bad boy out when I have a PC with a decent amount of (read: "any") GPU.

How about you?
