what do u mean u didn't like it ans it wasn't ur type of game? u can't have already played. it takes about an hour to download. and it DOES run on windows vista.
also; that game takes about an hour to an hour and a half to download. and it's free. but you have to have patience to find a good game and to download it. nothing happens immediately.
There is the old but free Conquer (co.91.com) as well as other games by that company. I think it's a Chinese company. I used to play it on my computer just fine, but I'm not sure if there is any shady activity going on there.
I used to play Runes of Magic too.... but frankly... if you didn't cash shop in that game, you couldn't remotely compete against the players that did... which made joining a guild and entering sieges... pointless... when your level 50 against another level 50...and there level 50 has 20k+ hp and +12 on all fully statted items... lol.... your 8k hp guy eats it pretty quick.
Lord of the Rings Online is now F2P as well. I've tried it and I was positively surprised, it was a lot better than I had expected. However, it might be a bit more complicated than some other MMORPGs out there.
