Yeah the game looks awesome and all, but going back to 2D linear style fighting seems like a step back from the huge open environments from the Budokai Tenkaichi series.
What do you guys think?

Well, it's in HD. There's a step forward. It omits the Buu Saga and the DBGT elements. There's two steps back.

Having only played the most recent Tenkaichi for a few battles, I can say this is a little less hectic. There was a lot of 3D fighting with squinting to see the player in the background in the most recent games.

I like Burst Limit. Is it a buy? Depends on how good you are at the game and if you've got friends to play with.

Well I find it very fun but I skipped the tenkaichi, my last budokai game had been budokai 3.

I think that it feels a lot like budokai 3 which is probably why you like it so much.

Considering there were over 100 characters in the last two games, and then there are only 20 in this game, it feels like a let down.
