System shock 1-2 (Seriously, why the heck did these games not sell well? System shock 2 is the best shooter ever made (it is not a pure shooter, much like Deus Ex, it has a strong CRPG element))
It is the best game I've ever played (the only reason I play Dead Space is because sometimes, if I'm drunk enough, I can fool myself into thinking they remade SS2), but there's a difference between underrated and underplayed. Anybody who's actually played it puts it in the top five.
Arcanum is underplayed. Every reviewer talked about how it had the most iterations of character creation they'd ever seen (beat it 7 times-each with a completely different character) and a unique world, but nobody bought it.
Alpha Protocol was underrated. I see alot of it in Deus Ex:HR, especially the talking duels. And misplaced boss fights. It just wasn't as flashy and had more bugs. I can forgive the bugs because none of them broke the game for me, and I beat it 4 times. But the end level was kinda...retarded. Which stood out in such an otherwise intelligent game.
Vampire Masquerade: Bloodlines was massively underrated. Story and gameplay were great, it had a somehow fresh idea, and the graphics were great for their time. It just had some bugs so people didn't play it, but if that game had gotten a console release, Troika would still be around.
