#50. BIT.TRIP BEAT (WiiWare - Also on iOS, Windows, Mac OS X, Nintendo 3DS, Android, Linux)
What drew me to this game was the colorful visuals, and retro style. I had no idea what type of game it was until after I played it (rare these days for me); I had only heard that it was this cool WiiWare title. I fell in love with it instantly. It was a real game, pure 100% fun. No realistic graphics, cut-scenes, voice acting, or any of that other stuff. It was a game that knew it was a game (also rare these days), and that's part of the reason why I love it so much. Also, DAT 8-bit music!
