To be fair Trove isn't a bad game. I actually think it's a fun little game and a decent time killer.
My only issues are that it has horrid FPS issues on PS4 sometimes and the cash shop is bloated. And they use that marketing gimmick of "10 million players" like FF14 or GW2 does. It's all fine and dandy saying 10 million people played your game but that most certainly isn't active player numbers.

I some how doubt the other 9,995,000 "active" players are on PS4, XB1 and Non Steam combined.
But yeah I agree. If Trion didn't have Trove their heads would be just above the water.
