Which genre of games are the best?

The two main genres I enjoy to play the most are FPS and RPG. Well, ok, I also like to play some TPS's but I play FPS's most of the time. Its just that their interesting and I like the action. On the other hand.. I enjoy RPG's simply because of the great characters and story.. its interesting to dive into a world that you haven't seen before.. There are some examples: FPS: Half Life Team Fortress 2 Battle Field 2 Deus Ex RPG: Final Fantasy 9 Breath of Fire 3 and 4 The Legend of Dragoon (ps1) White Knight Chronicles.. I actually enjoy most game genres except for one. Sports.. its the least interesting one out of the bunch.. those games are playable but thers nothing memorable about them.. their simply just there...

I'm an avid fan of the Diablo trilogy, therefore I should be liking the RPG game, right. This game had been my all time favorite and still my favorite to this date. Strategy games will come the second as Red Alert is my second best game of all time.
