q3map2 is based off of the the code for q3map, which is an id product. which means that while q3map2 isn't developed by id, it uses their code, which will need a lisence.
ydnar did post in that thread, but it reguarded the cost to lisence the tools, $5k, and it was after it was established in that thread that a lisence would be needed to use it commercially.
At $5k, if those tools were exactly what i needed for what i wanted to create, I'd create the game, not worrying about it for the time being, and get the game done. If the game ended up finished, and a demo of it seemed to gather enough public interest, then i'd purchase the license and start selling my game. It's not that much money. So in a way, I agree with Keless, don't worry about it for now.

ouch. I see.q3map2 is based off of the the code for q3map, which is an id product
Reading the readme thought was not based in it...
Then it leaves it all to getic bsp editor and compiler, and the bsp halflife type loader that is being made... And using of course then Quark+zhlt compiling tools to output the bsp.
