well I have to admit I've played a few FPS (First Person Shooter) games, but admittedly you do have a point Raion.
Afterall it's a bunch of gunplay, and killing people and lacking the necessary diplomacy that Alpha Centuri and others happen to carry across.
Of course as long as the FPS exist, then there should be some clue as to which ones are worth playing. (Afterall some actually put puzzles into the game, and you might even Term LARA CROFT as one of these)
I played one recently on a friends PS2 called RED FACTION, a kind of Beaten and dying miner fighting against the establishment that has tortured his comrads.
It had more of a plot in comparison to Hitman Codename: 47, which is pretty nasty, since your not saving the world from a evil and most definitely hostile alien race, but are out knocking of people with a sniper rifle, or creeping up on them when they are in the shower and grotting them.
Personally I want more STS (Space Trading Sims) flying to distant worlds to hack into a blackmarket mainframe, and sell the guns you stashed under the toilet on deck 3A of your Plasma driven X-Alpha1 Cargo jet craft.
(don't forget paying that UCROE [Universal Craft repairs of Exagile IV] insurance, that way if you break down or get shipwrecked in a lifepod you'll get picked up.)
