I've always played multiple MMORPGs, starting way back in 1999 with AC/EQ. And, I'm usually testing another one on the side. I do love variety.
The other players I associate with in game (unless I'm at an RP event, this is mostly RL friends/guildmates) aren't the type that talk down about MMORPGs. Though, I will roll my eyes (and bite my tongue) at comments of WoW that I overhear, especially from those who have little experience with anything else and act like it invented the genre. I quit that game less than a year after launch and couldn't care less what it has done since then.
I'm really looking forward to TSW releasing soon... will have my perfect trifecta of MMORPGs then.
LoTRO (lifetimer since launch) for my Traditional Fantasy.
SW:TOR for my Sci-Fi Fantasy.
TSW (lifetime bought) for my Modern World.
Also, YAY for 3 MMORPGs, only one with a monthly subscription.
