Well there are always private servers for Aion & with that there is no monthly fee. Here's a link:
http://infiniteaion.com/index.php?page=index2.php? I think it's a lot of fun but I got bored on retail cause at the time there wasn't enough player content but I think they added an expansion that included housing & mounts. Least that's on retail not sure if that's added to Infinite Aion yet. I also like Lineage2 play on a couple private servers on there as well.
got bored with Aion because there wasn't enough quests to level up without doing all the quests and
grind between... and there was no end game to look forward to except the huge pvp battleground (and I don't pvp).
