Pirates of the carribean online is pretty good, not to mention a good sized community and helpful admins. It also has the occasional code for a super-powerful weapon for members, so nobody has to grind too long once they get into upper levels. Not only that, but as the game gets older, they up the difficulty slowly, so those weapons can be the key to winning giant battles.
Only if you don't have membership. Honestly, i was being to much of an advertiser. If you don't buy the membership, it's actually pretty darn boring. (and THERE IS MASSIVE GRINDING for NON-members.)
There is a website called mmohut.com that i use to find all my MMo's they have Free to play, browser based, free trials, the works. no bugs and on most of the videos, a guy actually demos the different MMo's for you to get a look at it before you download. the website has no viruses and even has links to the games websites if you choose to download it. its a valuable resource for all gamers so i suggest giving it a try
oh btw SWTOR gonna come out soon.. It'll be a subscription (pay per month) MMO, as I heard, but personally I can't wait for this game P: it's from BioWare <3
I say combat arms,Crossfire,Dragon nest,Shaiya,Grand Fantasia,League of Legends,Eden Eternal and Aika online. I say Aeria games makes good MMO RPG games and Nexon too.
