i've played of ton a them.

Perhaps you may like Age Of Conana, the combat style is a bit diffrent. Wasn't for me, but it might be for you.

EVE on-line is also a bit diffrent, the combat system is extrmely blane and boring, however the rest of the game if your in to playing the market and building/crafting trucking etc, then you may like that one. Just note this game has a really big learning curve you will need to RTFM a good bit starting out.

Other then that, I find just a break and playing first person shooter games is nice. Just head some where like File Planet and download demos for free, play them even on-line for that matter and have fun.
