All in all a good game.

Just like Pokemon, but only one character at a time.

Also you upgrade the Hero's powers using Gold.

Mostly Pay to win but you can download Modded APKS for mobile phone or Modded Saves for JailBroken Iphones and Ipads. Just Google them.

Basically, there is no end to the game as far as I know and the end game that you can do is to just collect all the Hero in the DC universe.

Are we talking about the fighting game on pc and consoles or free game on mobile?

Yeah, God Among Us is pretty good. But you shouldn't play the multiplayer if you aren't good at combos though, but hey, it's great with friends
