I'm looking for a free MMORPG(ish) type game to play, money is not the question, If I like an mmo I play I dont mind spending a few bucks on it after I play it a bit, and deem it worthy.

I've heard and seen many Maplestory things over the years. Any1 ever play b4? I noticed on one site there was no PvP though, also I could not find if the cash items unbalance the game at all either...

Also if anyone has any other decent games they think I should google post them. Although I'm looking for a system requirement like diablo 2's I'm using an old computer atm.
