RPG's, no doubt. Pokemon, Xenoblade, MH, Skyrim and many others support that claim. :D

RPGs and Strategy RPGs

Then come platformers, puzzle, racers, fighters, action/adventure, action/beatemups.

1. Action RPG or whatever genre Zelda is (Arkham City, Prototype 2, those kind)
2. Games with 4 player local multiplayer (Smash Bros, Mario Kart, WWE Day of Reckoning & PSABR have taken much more of my multiplayer time than any online mode of any game)
3. Platformers (mainly Mario actually)
4. RPGs
5. I don't particularly play stealth games that much, but I love action games that have a stealth option, like the Arkham and Uncharted series. Zelda (yes) and MGS gave me a love for stealth, but apart from MGS, I'm not sure I could survive games where the MAIN focus is stealth
6. First person adventure games. I've never beaten the campaign of any COD or similar FPS, but I've beaten games like Portal, Metroid Prime and Red Steel 2.

What is this 10 minute double post black magic!?! 

Just checked all the games I've played this year:
1) Platformers
2) RPG
3) Shooting (mostly 3rd person)

RPG's, different variations of it.

Action Adventure, in this case Metroidvania.
