If you want some good games, NTreev has some... average... games. It's great to play, but if you purchase premium items and credits from them (NTreev points), you will be surely disappointed with their "chance" items, or "Gacha(pon)." Your chances are low and just when you think you tried and wasted $20, a 2x gacha rare result rate will happen... right when NTreev has the money to pull a marketing stunt to.

Good games, bad money-waster.
