Let's take this serious. I present you a Game that i already play for some Years now. It's called Lunia Chronicles, but everyone just calls it Lunia. It's a MMORPG with a cash Shop. But the Cash Shop dosnt rule everything. The Game is very balanced. The cash user just get 1 thing better then the others : They got their Items faster. For the non cash-user you still can do Quest where you can obtain cash items. And if you dont want to do Quest or upload Astros just buy the Items with gold. Since cash items can be traded.
Currently "OgPlanet Europa" hosts the Game "Lunia". With many Events a nice Community that helps each other and many more things you should find out ( If you want ;> ). Also we often get Updates or free stuff event (most time giving away cash items).
Lunia is one of the Games that has 0 hacks because everything is serverside and if you still got problems with someone there... just write a ticket. The Support team is nice and you get youre answer fast.
I could tell ya much more about "How great this Game is". But if youre interested .... i leave the link's here. And if youre not sure and got Questions left just tell me :)
