Most underused genres?

Westerns

Turn based - Party management RPG's

Skating Games

Strategy RPG, God Games and FPS Arena. Even GOOD rpg games would be great cause for now they're all shitty (except Dark Soula)

Date sim

Nonfantasy rpgs and turnbased stuff! And adventure/rpgs like quest for glory.

The Run Factory genre, lacking the proper vocabulary.

RTS! This genre is dead. Now we only have tactical games like Total War series or games like Starcraft where player (most probably from Korea) with highest APM(Action Per minute) wins e.g Starcraft. I want game where i can build buildings, defences and rushing is suicide. Where's new AoE? Age of Mythology? Warlords:Battlecry? :|

I would like to see more Tactical FPS like Swat and classic rainbow six. and a different kind of RTS/City builder/God game mix that you can do with friends and shit in a more lively world rather than just for a 30 minute match or so.

Zombie platformers with roguelike elements and tactical combat in randomly generated dungeons. With kittens.

I'd love to see more point & click adventures. The non-action ones. I think that the closest we have to point & click adventures are Hidden Object games, but that's just not the same.

That, and stealth games, as some people already mentioned. We sure could use more pure stealth games, like the old Splinter Cell and such.

Survival Horror games, with the emphasis on Survival. Anything where you aren't at best trying desperately to conserve ammo/resources does not count.

Point and click games.

RPGs with cyberpunk, sci-fi and modern day setting.
Survival horror games like the old Resident Evils, with exploration, ammo management and dynamic camera angles.
Spy games like Alpha Protol and The Operative: No One Lives Forever.

Not really a genre, but a setting. Pirate/colonial games.

Real Time Tactical games, like the Commandos series

I really want to see a good turn based tactical game whatever you call it like fallout1+2+tactics/paradise cracked+power of law/e5+7.62/silent storm but not castrated like the not so new X-com:enemy unknown.

I would love to see an openworld detective type game. I think that would be awesome. I've never done too much looking into if there are any though, so if anyone knows of some, please let me know! Also, if you haven't played it yet, KeeperRL is a pretty awesome God-Type game, and it's free, so it is good to waste some time on.

Pirate rpg's

real historical cRPG without elves, orcs, dragons, gaytalk, magic and shit

Turn Based FPS

Male sex sim.

definitely zombie/post apocalyptic

A horror game that doesn't rely on jumpscares
