I've played all the major MMORPG's out there (WoW, DAoC, Ultima Online, FFOnline, SWO, Warhammer, Eve etc.). STO is the one for me. I love it!
So far I'm impressed with the community also. STO people seem to be, in general, a far more mature crowd than one typically sees in other MMORPG's. This is my RPG home. I'm here to stay.
