Yeah i've been playing this since launch day. Its free but there are catches. Fun either way. I just want them to update it already(no practice mode, based on my arcade runs there's only 5 possible character unlocks(you start with 8 characters)) Character customizing isn't in here but I think they want you to buy TTT2 for that.
In terms of gameplay its the same as TTT2 just w/o partners and sexier fx.
There aren't many characters available for it at the moment, but the point of this Tekken is that you upgrade your character via skill points when you level up and increase your HP, AP and also your vigor, which increases the chances of pulling off a critical hit
