Reality Factory

Hi. I couldn't find any definitive information about this with a google search: is it legal to use Worldcraft 3.3 to make levels for a reality factory game that will be sold? It would be great if someone could let me know.

Yes, it is legal.

Awesome. I should have asked in my first post, but could you maybe refer me to the information (e.g. the part of the license, if it's in there) that says so? Not that I don't trust you, but I just want to make absolutely sure.

There is no part of the license that says so - it has to explicitely say you cannot if it is prohibited. 3.3 doesn't say you can't, 3.4 does. You own the copyright to the work you do in the program, and the only reason you cannot legally in 3.4 is because it says that you cannot use it to create maps for non-Valve games. If you disobey that part of the license, the license becomes void, and thus it reverts to normal copyright law, in which (insane as it may be) you didn't have the right to download or use it. Thus the license is what grants you the right to use the software, and if you violate it, you lose that right. No such clause exists in the 3.3 license, so you don't lose your rights to use it by doing so.

Nice 3.3 here I come.

Good enough for me. Thanks alot for all the help Andy, it is appreciated.
