Yer, it's going to be, I'd assume you're going to be spending the crowns you earn in game for more cosmetic stuff.
The only way I could see them buggering it up is if they add stuff like paying for new super spells... Even though I would totally pay for a super that drops meteorites that hatch into reapers for awesome chaos.
Well it is too soon to say since it is not out yet, it might turn nasty, I had that bad experience before with free to play games. Like Microvolts, this game was really fun until those extra benefits people could buy with real money like more speed, more health, more ammo, now it is just awful, I wasted my time there.
I might check it out when I get a key but honestly I only signed up to help people get free Magicka, which isn't going to happen because apparently there was a time limit to that and not enough people signed up.
I think it's likely that I'll get it. I've only heard good things. The only thing I worry about is its lasting power - what it's going to do to keep people playing long-term.
