This game is a town building, and the main difference with other similar games is that you don't have to defend your town vs other players. Your opponent mostly is the monster in open world and dungeons. So no town expanding. Instead, you can focus on development, build a team, and fight other players in siege war and the arena.
I won't say Im a f2p. but I don't spend much ingame beside battle pass and some cheap offer in prestige. No gem brought at all .Still I managed to be one of the top player ingame right now. With full 5 star teams. So yeah, not that p2w.
Game is hard and confusing at first cause there is next to none tutorial. However, once you get a hang of things, building a team and trying heroes combo in the arena and vs npc is quite fun. The battle log is hilarious, especially with chaos involved.
The dev is small, but they do listen and actively try to fix bugs and implement change to the game.
Overall, the game is a good time waster, and have potential.
Also, as at the latest update, we have a story mode.
And now, the dev has decided the honey moon is over, and turn the game into a money grab.
