http://tk7.tekken.com/fighters character roster, some bio and standard 2 costumes. Kuma (whom i will probably main) has a sick 2nd costume lol. And i love Katarinas design, so i might try her out too if i get bored with Kuma. But unfortunately there are so many good character designs in this game, i have a hard time picking anything. Alien Yoshimitsu looks sick, Ling Xiaoyus 2nd costume is hella cool, Samurai Heihachi looks like a god, Shaheen looks really fucking cool (i can really dig certain middle eastern stuff), Eye patch Hwoarang looks like a bitch and i love it. Paul is a beast, his death fist alone makes him so respectable and tempting to play, and same with Steve, pure boxing makes me horny cause of Hajime no Ippo. Oh and also waifu Nina looks like something straight out of kill bill, too good.
And then of course on top of all this, unlockable customization seems to still be completely fucking free, no 5$ alternate color schemes etc. You unlock completely new parts and shit all for free, afaik no microtransactions at all. And i dont even mind paying a bit for some new content, but its still very commendable. Though i would actually want to see something like dota 2, where you can buy stuff and the money spent goes towards tournaments, which is straight up the best system ive seen.
