This game is fun as hell lol. I play it everyday. The gameplay reminds me of T5DR, which I LOVED. I actually kinda miss bound, but at the same time, I'm used to not having bound since I've been playing Tekken since the very beginning.
Tokens are a bit annoying, but i don't mind it too much. Even if you run out of tokens, you can still play online or arcade of you have premium tickets. The tickets are actually better than the tokens imo. If you play arcade with a premium ticket, you gain more experience and gold. If you play online with a premium ticket and win, you gain a premium ticket back, whereas if you lose, you gain more experience but lose that ticket. Not a bad trade off.
I've already unlocked two characters, Steve and Brian, both of who I used in previous games. I have no idea how to unlock them but I know you have to gain a certain amount of gift points to unlock someone. Alisa and Leo are unlockable as well. I'm hoping heihachi, jinpachi and orge are hidden as well since you fight them in arcade mode.
Since its f2p, Harada already mentioned that he can update it whenever he wants. He's already hinted to more characters, a vs mode, training mode and more. I'm pretty sure more characters are coming because you see characters like Nina, Anna, Jun, kuma, and Jin after you beat arcade.
Overall, it's a good game and I will continue to play it Alot.
Edit: I LOVE the critical arts and special move. It adds a new depth to the gameplay. I'm guessing the red move is the special move right? People have been crying about it being too powerful since it's invincible and damaging, but these moves are Highly punishable on block. It's a double edge sword, very rewarding on hit but consequences on block. The critical arts are the blue ones I'm assuming. These are ridiculous lol. The damage that can occur if you get a critical hit can be absurd, especially if you are a high level. On top of that, you can still land a counter hit, with is already damaging, and still get a critical hit on top of it. Not too mention, Lili (my main) has a critical art that is a combo starter (d+b 4), so critical hit + counter hit + wall Carry combo + wall combo + oki = lol.
