5 stars: It has a feel of heroes of might and magic III(HOMM3). A game that I played a lot back then. For sure, it's not as good as HOMM3, but the type of combat is the same. I like the game at the beginning. After a couple of weeks, honestly, I enjoy it a lot. Rewards for the weekly events are very satisfying. FYI Might be a deal breaker for some, but there is ads that you can watch to double your earnings.
4 stars: it's like Heroes of Might and Magic but you can't actually Build Your Heroes you just get them as you go along which is kind of weird so far so good but I wish they would let you build some Heroes in your Castle or at least do things to get them but overall I'm enjoying it.
2 stars: Very ad heavy unless you are a pay to win. Not worth it for idle gameplay. The gameplay is great, for the most part, but eventually you hit a point where you either need to pay more and more to get and upgrade units, respawn them, and access the entire map, or you have to stop playing for several days/weeks in order to receive enough rewards to upgrade a card and beat one more enemy troop, only to do it again.
2 stars: I really like this game. Gives me nostalgia. I played the game hard for a couple weeks, but now I'm stuck on the 3rd map with 99.3% completion, but the last dungeon is too hard to defeat. I don't really get why the next map won't unlock yet because I think the 2nd and 3rd maps unlocked when I was only 60 - 75% completion on the maps prior. I really like this...
