Gameplay is fun. If you're disciplined it it capable of being a f2p player. However, this game is riddled with bugs and leaderboard exploits. Most rewards are tied to the leader boards so this creates a big issue. Most recently I donated 3000 cores to an alliance event that was bugged and taken advantage of by cheaters and received 0 compensation. As a light spender I realized this company does not care for its player base.
