Err... Tekken Tag 2 is just like Tekken 6, SFXT is just like SF4... basically. Devs have their own style. And MK9 got rave reception.
Now I didn't care for the latest MK and stopped playing almost right after completing story mode. If the gameplay here is as clunky I might not last much longer, but atleast DC characters with DC story is way more interesting than the feuds of MK.
The DLC system is annoying, but most games do that now. It's basically either accept it or don't play anything else than indie. I've decided not to buy certain games because the DLC/DRM/Whatever system goes over the line but costumes and mini-missions aren't enough to sway me. The extra outfits look nice, but 1 is enough, while 50 would be the optimal.
