I've played:

- Tekken 3
- Tekken Tag Tournament
- Tekken 5: Dark Resurrection
- Tekken 6
- Tekken Tag Tournament 2 (although I haven't played much of it)

Tekken is really the only fighting game that I bother with. I'm only a casual player though, so I'm not one of those that learns every single combo for every single character. The only 10 hit combo I know is for Lili...which says a lot about how bad I probably am xD

Also Vyk, it's Street Fighter x Tekken. Tekken x Street Fighter was announced but it's probably vapourware at this point, unless Namco plan on releasing it after Tekken 7.
