No. 41: Tekken 5 (PS2)
http://gamrreview.vgchartz.com/game/2346/tekken-5/
The Tekken series has been my favourite beat-em-up franchise since Tekken 2. This represents the best of Tekken (with the possible exception of Tekken 6 which I've yet to play). It takes the Tekken formula, and optimises it whilst rectifying some of the annoyances of Tekken 4 (e.g. small arenas). The only thing that could have made this better was if the brough in the tag mode from Tekken Tag. My favourite 3D fighter.
