I should try and get into the next one. Hard for me to get into anything other than Tekken.
This one should have a pretty cool interactive story from what I've read, and Akuma plays a large part. As far as Tekken X Street Fighter, either it will happen or it will just be some expansion to 7. Akuma actually plays like a Street Fighter character. When I went to the last Tekken 7 FR tournament some Street Fighter players were able to pick him up with little knowledge of Tekken right there on the spot.
I'm loving the addition of Akuma, for this reason:

As far as being bad at Tekken, if you ever decide you want to become good hit me up and I'm willing to spend some time training you or anyone else here. I am really involved in the Tekken community, it's probably one of my biggest passions, and the more players that get into Tekken the better.
