Engine - Legal question
Posted 16 December 2011 - 08:30 PM
I am currently working on a horror game. The story, concept art, level design and a few 3D models are all completed (but are most likely subject to change later on).
The build of the game I am working on is only for promotional use to get funding, for example, a free to download demo on a funding website like Kickstarter.
Now I'm looking for an engine to work with after finishing the demo.
These are the engines (that I can remember from the top off my head) that I am familiar with: Source, Unreal Engine 3, CryEngine 1-through-3 and have lately been trying out the HPL2 engine (designed for the horror genre, after all). I am currently working in UE3.
Question: What engine would be legal to use? I plan on selling the game, and I am looking for an engine, hopefully similar to the ones listed above, that would be legal to use.

I mean a game, using a some engine, without getting sued or something. A licensing fee is of course a necessity, but they are mostly as high as a months pay. A free to use, sell, etc. engine.
If I remember correctly, the id engines are under a GNU license. Would that make them usable in this situation?

Rather than deal with legalities first, see if the engine you want to use is something your and/or your team is comfortable using. There's not much sense in aiming for a 'free' engine if in the end you hate working with it. Having said that, there's typically 3 popular license schemes out there today. GPL, LGPL, and MIT/BSD. It's best you read the fine print to make sure that is something you can follow. ID tech engines are released under GPL, which is the strictest of 'free' licensing schemes. Can you use it for commercial purposes? Sure you can, but read the fine print to understand what rules you must adhere to. In general, commercializing GPL software is not strongly recommended.
