A fighting game. Simply because of the logical longevity of the game. With an FPS you will eventually be able to memorize all the spawn points and all the locations of all the weapons on all the maps and the times of all the respawns and with time you will be able throw grenades/headshot into every spawn right as they come into play. With an RTS you will eventually be able to build an army in the most mathematically efficient way and move your army in the quickest path with the least risk towards the enemy and crush everyone. With an RPG you will just achieve 100% completion and then what's the point. With platformer games, given your entire life, you will be able to complete every challenge in the fastest possible way. With hack n' slash games, you will eventually master the enemy AI and develop combo strings that are unbeatable.
However, in a fighting game (A good, cleaned-up, glitch free fighting game), there are no combo strings or other methods that are totally unbeatable. There might a most efficient way to maximize damage in minimal time, but there's no way to maximize damage, minimize time, and then leave yourself totally invulnerable. So you will continue on to be uber-skilled and godly not because you are mathematically unbeatable, but because you are completely in-sync with the game and know it inside and out. But of course, some psychotic player will come along and beat you, but luckily you have your entire life to practice so eventually you will become the most skilled gamer in the world. Hooray
So in conclusion, probably SSBB
