Spacelords

The game is Free-to-Play.

That said, it's also forced 4 vs 1 PvP with an absolutely atrocious leveling up system. The PvE stuff isn't all that bad, but the PvP is a bad joke, and with how much damage you do and take tied directly to how much you've leveled your character, it's easy to end up in a situation where you can't really do anything as the lone "Bad guy" in PvP, or put up against a player that easily annihilates your team over and over.

I don't think I've ever found myself wanting to like a game so much yet being unable to.

I love everything about this game but the f2p mechanics ruin it. This game has received a lot of updates since I last played it and is still getting more as far as I know, but I personally don't have any hope left for it.
