they want it to be open source so that they can’t do a unity
That has nothing to do with open source, that has to to with licensing, which I’m pretty sure isn’t an issue anyway since I think Unreal versions are tied to specific license versions, i.e. if you download the engine under one term, thats the only one you have to use
But the code is easily visible and you can compile it yourself. If you say “I only run software I 100% knows what it does because I can read it’s source code” then Unreal Engine fits, it’s open source.
Under that strict definition, software under the GNU GPL would not be “open source” because the license stays with the code, and is not truly “for any purpose,” which is the same deal with the Epic license: you may use, study, change, and distribute the Unreal source code, but it stays under Epic’s license.
If you are talking about the FREEDOM to fork and publish and share and whatever, then you mean Free software.
Story is meh but lots of people will say how the open ended nature of Crysis was fun and a pity that it was removed for a more linear CoD style in Crysis 2
