A Tekken 5DR remaster would be preferable, though I loved Tekken 6's Scenario Campaign.

T5 DR I liked because it gave the best character(Lili) and the darkest stage(Ominous Mist) but I would say T6 I felt was more fun. I wouldn't mind a collection tho since it would be more game and screenshot material xD

I'd buy a TTT2 remaster if they'd remove the bullshit characters like Slim Bob and the other copy-paste moveset characters.
