It all depends on which fighting engine you like. If you like Netherrealm's fighting games, then keep on going with them. Tekken 7 is also great game even without all the DLC. It is defintely worth the price of admission as of right now. Tekken is very easy to pick up and play despite claims of it being difficult. . Soul Calibur and Dragon Ball Fighterz are also great games. If you can get the arcade edition of Street Fighter 5, the game is not terrible. Most places do not sell the arcade edition in stores.
I like the Tekken series. But, MK is my roots so I'll have to recommend MK on PS3. That game is also on the PSN game rental if you want to stream it instead of rolling out your PS3. I have not tried any DBZ games since the PS2. How are the DBZ games? Better than PS2 Budokai games?
Hey! My favorite fighting game is MK, but I don't like the last one so much, so I'd recommend MK XL. Take a closer look at UFC 3, it's the best fighting for me. The only disadvantage is that your friends who don't often play UFC 3 will have no chances against you. MK to chilling with friends, UFC 3 for multiplayer.
@gcfreak898: Dragonball Xenoverse is more of an MMO than a fighter. Dragonball Fighter Z is a simplified version of the fighting engine used in Guilty Gear. The PSN holiday sale has the game going for cheap. Most of the DLC characters are going for half off. The story mode is cool albeit repetitive. One of the best fighters I have played in awhile. Now is the perfect time to go for it.
