Might be worth it soon though now that their opening the community live thing. If your game is good enough you actually get paid when people download it.

Which brings me to a completely different question I had in terms of copyright/patent/whatever.

How different do you have to make a game in comparison to another game to be able to call it original? I'm a huge fan of puzzle/strategy games, so I have some idea's, but their basically knock offs of whats currently out there, although I have my own flavor to them. Its really hard to innovate the block concept, as there's only so many ways to move/rotate and place blocks on a screen.

I wont give away my sekret sauce, but as an example, compare puzzle quest to bejeweled or to jewel quest. All have the EXACT same concept, they just vary in different things going on. Did they have to license from the bejeweled people? Is it different enough that it is its own game?

Or what about the tower defense games. What if I wanted to make my own version. Since that was a free mod for WC, am I free to make and sell a different version, even though the concept is exactly the same?

Basically I dont want to spend a month or two making games, only to find out I'm about to be sued for stealing someone elses concept.
