3 stars: Good, but this is for the game it's self not for the developer because they are creating a lot of event in-game that make you to pay the money for them, otherwise you won't won anything from it, the Epic character rate will decrease if you reach more higher lvl, it will make it harder to progress since you need better hero. Final, you can get diamond everyday if you do all daily activities.
3 stars: A fun idle-ish game marred by a stingy, boring gacha. The gacha would be okay if it wasn't so tight with purple characters... and since you need many, many, many character dupes to level your characters, f2p becomes a slog of stalled progress with rare chars you've managed to pull sitting at a level cap. Except there's no real incentive or excitement to whale, because you'll still pull mostly useless green characters.
4 stars: This game has the same setup as AFK arena, and I'm not complaining because I like that game and love One Punch Man. It's unfortunate that the difficulty starts to spike as you get further on. But I think that's mostly me being impatient and not saving up diamonds over a few days. I've spent too much on this game, and while I love it to death, I wish it wasn't as difficult and pay-to-win as it is in the higher difficulties.
3 stars: The game is 99% copy-pasted AFK Arena with updated graphics and a popular franchise. The IAP is very predatory, but occasionally you will get a good offer. Have spent around 20$ cause I enjoy the game, but you...
