wow, that list would not be my choice

Habbo Hotel !?? Oik, its interersting, but not something I would keep coming back to.
Try these...
9Dragons, Rappelz, Martial Heroes (i tried them and won't return too soon due to how poor these game worlds look - its like they quickly create the terrains, dump crits of various level groups all over the place and then spend some time to create nice looking player characters) . .this is just my opinion and I probably didn't give these games enough time in-game, but if it can't catch me in the first few levels I move onto something else, there are just so many MMOGs to try
Last Chaos (still downloading)
Archlord - you need to buy the client, but there is no monthly just like Guild Wars, and unlike GW it is not just one instance after the other. If I where to play a free2play game this would probably be it, but I bought LOTRO so thats where I'm spending my time atm
Oh, almost forgot bout Dungeon Runners ! You have to try it, this one I will be playing again.
