I absolutely love YuGiOh and the games released for it. This game was amazing for the first week I've played it. It was fairly easy to rank up and get gems and whatnot until it wasn't. That's partially fine. It's expected for XP limits to get harder to reach. But the issue is the reward gets smaller and smaller. For example, when reaching level 2, you receive 500 gems but reaching anything beyond level 16, you now receive 50 gems. Among other things, Konami is failing to support players.
