I like all genres.

Looking back at the games I have enjoyed the most, it has been Platformers. I like fighting games aswell. Love action adventure type games. think Uncharted/Zelda.

Like rts, think Total War.

All types of games. I think the genre i have probably played the least on that list if FPS. and thats because I dont tend to enjoy them that much. Just meh

Strategy: TBS, RTS and SRPG.

JRPGs and WRPGs are too different enough to include them together. I love WRPGs while mostly disliking JRPGs so I could not vote. Face it people they are two very different genres.

RPG, RTS and FPS

Really hard for me since I am quite fond of point and click games and aswell plattformers. I'll go with plattformers.

Thnx, i also think so
But what about yours HappyD?

FPS games first and then Action Adventure games like Zelda second.

Pretty much identical to yours, but I'll go in detail :)
Zelda/Metroid-esque puzzle action adventure games are my favourite for the single player. I'll include point and click adventure games here :3

Then it's old-school RPGs (FF) tied with RTS (Warcraft III, Starcraft) and Dungeon Crawlers (Diablo, Torchlight).

3rd fav is Platformers (3D Mario, others retro Megaman, Ninja Gaiden, Castlevania, Kirby's Adventure).

Lately I have been enjoying FPS in Borderlands 2, but that's because it's just so awesome in how it takes from Diablo in weapons and leveling.

On multi, i would go with fighting games, RTS and FPS.

Sports and racing games are the icing. 

Action Adventure. A great action-adventure has the action of a shooter, the story of an RPG and the intelligence of a puzzle game, sometimes even with some platforming thrown in.

HappyD
Classic FF-esque RPGs are my second favourite
but i dont know if like more 2D plataformers or 3D ones................i would say 3D plataformers because of the adventure factor
i like every other genre you named also, except im a turn based strategist, CIV FTW!!! Screw AoE!!! xD
