That is the coolest 2D game I have ever played. You can even play it online against other people. It's for every platform I beleive. Came with my SuSE Linux and I have it on Windows. I beleive it has it for Mac too.

Woah, ninja edit.

Yeah Wesnoth is pretty cool. I tried some single player but never really got into it. Maybe a BYOND game could be set up?

If I were to make a fangame of it, would it have to be open source as the original is?

Only if you used GPL resources when creating the fan game.

I don't see why you'd bother though. Why not contribute to the actual game instead?
How can anyone regard Wesnoth as fun?

cuz it r!1

That's like saying "How can anyone regard Battlefield 2 as fun?"

Or just make your own strategy game that liberally borrows from all the Tokienesque fantasy that has come before. Much like Warcraft, Siege, etc.
