I think people aren't giving this game a chance. It's BARELY starting and the bad reviews begin. Let me give you the HONEST review if this game.
If you've EVER wanted to pilot a real Gundam, this game is for you. The mechanics are based on what it would be like in real life. Almost like Versus which is another Gundam game.
You don't always have to spend 30 tokens, sometimes you get free 30 gachas on events, sometimes they are 15. You get 3-10 tokens each day depending on how many missions you do and how well you fight.
In my opinion this game is pure instinct/skills. It updates every 1-2 months more or less adding new units, fixing bugs, adding maps. I think they might add campaigns hopefully because it's predecessor SD GUNDAM ONLINE had campaigns.
