Use Indie or Commercial license?

#1 If you're the only programmer messing with the actual engine source code (not the scripting code) then you can use the indie license, providing you make less than $250,000. If you make greater than that amount, you have to go commercial. If you have content from other artists, just make sure you have rights to use it commercially.

#2 Your publisher's earnings count toward that $250,000 if I remember correctly. Also, if you are being contracted out to do Torqe programming, you will need a commercial license -- or at least that's the last official word that I've read from GG.

#3 "(b) Licensee may not use the Indie License if the annual revenue of the Company employing, partnering, or affiliated in any way with the Licensee is greater than $250,000 annually. Companies that grow to greater than $250,000 annually must upgrade to the Torque Game Builder Pro Commercial Product License for each seat of Torque Game Builder Pro."

So don't buy it unless you're involved in a commercial activity with people making more than $250k/year.

Not a problem for a lone developer unless they're doing contract for someone else who meets this criteria. Or the one in a million shot that you start making more than $250k/year you can just buy the commercial tools then.

#4 Or if you're developing non-game stuff like educational software, simulations, TGE powered accounting apps, etc.
