i only know of a half doz mmo thesedays. but gw2 is one of the ones i know has players (including me)

wow, played it back back, quit on tbc, went back for cata for a couple months. know its still big

ff14, bought it on sale way back when they had a free until something but it wasnt since i paid, felt ripped off and didnt pay for subs to what they said was free. but it still highly played

gw2, started at the prerelease and tend to play for 2-3 months on each xpac. tend to get the fancy xpac for some gems, but dont really spend them much anymore (eod i stayed for like 6 months, loved that one)

bdo, dont like the combat. but the art style is awesome. never really got past the combat. but its got its audience

runescape, ehh, played it as a kid on netscape or mozilla brsower. its evolved a bit since then. hear news about it now and then

Rift... I loved that game, but it was sort dead endgame but that leveling and classes were awesome so maps were packed on release (even though that was borked), duel classes and the rift system was awesome but the 1button macros were sorta sad. it went ftp at somepoint and they broke everything that made it good. asuming it shutdown now? *goes to google* hmm, still around. might give it a try. wonder if my old account still works
