Your Most Played Series (by number of games played)

[Leadified]

Let's see, I've played all the classic Mega Man games, plus all the X games until X5, some of the Gameboy games and one Battle Network game, in total that would add up to... 17 games.

All the major Mario games except New Super Mario Bros. 2, so that's 15.
11 games in the Legend of Zelda series.
10 Metroid games (if we count AM2R which I totally am)
10 titles in the Metal Gear series.
9 Sonic games.
