Prime world is a dying game which does not address the matchmaking (which is broken) and the players that play on the Keeper side will sandbag every match in order to win. They enter with overleveled characters and stomp the competition with 4 and 5 man premade teams. If you are going to download this game, wait until they fix it first.
this game is ONLY good if you play it for as many hours as i did, if you play, play on the overpowered characters (listed by their brokenness Blademaster/Sesha, Witch/Moira, Nox/Vryl, Haka/Daka, Firefox, Cryo, or Jaegar/wolfmaster) because if you don't you'll get stomped and left in the dust. there are some of these heroes just mentioned that are raking in the resources because they are so easy to play, (i played my blademaster with crappy stuff on him and retired him when he was level 12 because i was so bored, seriously, he's immortal after level 13). I still wouldn't recommend this game because the heroes are so underbalanced and there is a definate lack of initiative on balancing the characters. Until the characters are balanced, my recommendation stands, don't play it if you are NEW.
TLDR: don't play it if you're new, you'll get stomped.
