haha, I went throught the exact same thing with another f2p game I play called APB. I didn't think I'd ever spend money on the game, in fact I'd be like "omg I can't believe he bought that" but not even a month later I started to get some stuff
Then eventually I start to get people complaining through pm saying shit because I'm a "premium" player lol.
When I have the time, Imma check this game out.
