Thanks for the info. I was kinda looking for something a bit different to D&D actually- I think Pathfinder and earlier D&D & its clones would feel like more of the same. I enjoy D&D but I'm interested in trying some different systems.
The Game of Thrones RPG and The One Ring have both peeked my interested, but neither seem to have more than 1 or 2 adventures written for them.
I would try a different genre entirely then. There are a lot of good sci fi games out there, Traveller, Eclipse Phase, CORTEX, Savage Worlds, etc... but the only one that I am aware of with a lot of scenarios written for it is Traveller.
Then there is RIFTS, and it has a lot of scenarios written up for it in RIFTER and the like.
Then there is a whole bunch of Supers games, with plenty of stuff written on the web for them. For a really different feel I'd suggest Wild Talents 2E.
Then there is Shadowrun, plenty of stuff written up for it to last at least 5 years of weekly play.
Then there is Legend of the 5 Rings, not a lot written for it, but you can adapt any D&D adventure to the genre and go from there.
Then there is post apocalyptic, such as Twilight 2000 and 2013 and Gamma World. You can find enough material to run a game for years too. Besides, all you really need to do is use Google maps, pick a location or three via Google, then decide what is going on there, and you have a game that will last a couple of months, probably. That is how we played last time, and it went great, plus the maps were incredibly realistic and even had 3D imaging. (Sarcastic humor about how awesome Google Earth is.)
