Best for me.. Uhh SoTNW Guild Wars and thats pretty much it for me.
Worst is MapleStory and Neosteam gosh that game is still overhyped on Onrpg I think and I just dont like it lawl i Got to like 34 and well dont like it.Well its not the worst but its down there since all the crap problems..
MMORPGS in general annoy me... they say they're doing something new... but in the end its just a new flavour to the same candy... yeah it's nice and all but in the end it still feels like the skill bar and click gameplay candy...
Though some are good like Antlantica, Concerto Gate, Dofus, Ultima Online (point and click but one of the first MMO's to make things different then kill everything), Huxley (MMOFPS), guildwars (skills arnt changeable in battle and require thinking) and thats about it...
Best - Guild Wars has got to be the best, hardly any grinding, just an amazing pvp based game...
worst - hmm, i can't say runescape is bad...cause it is kinda fun for a while....um...maplestory is horrible, bad graphics, bad gameplay, annoying f-ing little kid community...Atlantica was lost to me when they introduced the stupid stamina system...all korean grinders that are all the same lol, though flyff was fun for a while...
