Usually I'll pay a membership fee if I really enjoy the game. Otherwise I tend to shy away from micro transactions.
I used to soent alot but now not so much i just get the necessary upgrades to progress mainly cause when i quit i feel ripped off lol
I once spent 10 dollars on a game then I stopped playing it.. Realizing Im becoming too addicted to it..
The thing is not what i bought (mounts and other cosmetic items) but the fact at that time i changed accounts a lot.
ohh my when i first started i spent $1k to Perfect world online $500 to Rohan $500 to Forsaken world Intl. $1k to Forsaken world mobile $1 to Legend of nine tails $0 yet to Ragnarok journey waaahhh! now i realized i don't have money lol.
