I still play Unison League, but it's one of those games that's free to play... but buying gems does give you a significant advantage. For the most part, you can still earn quite a few gems just by playing daily, but when it comes to spawns, a lot of it is based on luck. Some people will get all the great equipment and monsters spawns. Others just don't get lucky. I'm kind of in the middle. I've gotten a few helpful things, but I haven't really hit the jackpot like some people have.

Overall, it's a decent game, but it does involve a lot of grinding later on.
