I occasionally play Runescape (my brother's char is over level 100, mine is somewhere around 50), I play Travian (I've got an amazing army right now =3), and I've recently gotten back into playing Maple Story.
I'd like to get into Guild Wars or World of Warcraft sometime, but it'll be a while, as I really don't have an income. And my birthday is in October.
If anyone posts, I'm willing to provide usernames for any of these games. I can also provide links in case you haven't heard of some of these.

I've not heard of Travian. But Runescape isn't that good, I used to play it years ago but my character was deleted with his R2H and Adamatine legs. Level 56. Couldn't be arsed to recreate.

If you get Guild Wars, it's a one time fee for the game Guild Wars.
You can pay for the expansions, but you can play them standalone I believe. Get the Original Prophecies Campaign first, not Factions.

Then join my guild! ^_^ I need to make it active again.

Well, Travian can be found here: Travian.
Simple enough to remember, but it's kinda hard to start off. It's slow, and not much of a player interaction game. But still, it's kinda fun.
Runescape has gotten much better since the olden days of 2-d graphics. I'm very impressed. Membership is actually worth it. Around 6 or so skills for members only, and many many quests for them.
If I ever get GW, I'll be sure to join your guild. =3

I don't do a lot of online gaming....Too lazy....lol

Runescape's the only one I've ever done. Haven't played it for ages, and it didn't seem that interesting when I did play it.

I play Puzzle Pirates every once in a while, too. It's pretty fun, if you like thinking.

GunZ, Maple, MGS: Online, Monster Hunter, RE: Outbreak 2

thats it right now for me
