There will be people disagreeing (I think) but that one game, Trove, I think it's dying. I used to play it before it got all huge on steam and everything was equal, but as soon as it got released to steam, BOOM, you had to wait in a queue for most of the time an hour to get into the game, and even that wasn't worth it because let me tell you something: it has it's pros and cons. Cornerstones are awesome, but crafting recipes are so freaking expensive sometimes.

The best part of the game is when you first finish a dungeon. You get brand new loot. at level 11, which is my level, the game is just grind after grind after grind... I once spent HOURS trying to get a new mount, which are arguably the most valuable items in the game, only to realize it was in some kind of weird hotbar thing in the bottom of my screen.

So yeah.
