I am downloading this free to play MMORPG at te moment, do any of you guys know it? And it is worth playing at all?

Yes, and yes if you like some kinda fallout mmorpg ish style game.

It has some cool features but it seems kinda grinding to get some money in that game.

I've dled it, but I can't really say I've played it.

Also, possible to download via Steam, unless I'm mistaken.

Yeah, it's on steam as f2p aswell. Have it there myself.
