What are /r/OpenSpaceProgram's favorite Products & Services?

If we're going to make an open source KSP-like game then I'd prefer it if it were fully open source, meaning that every component that we use should be licensed under either a permissive license like MIT/Apache/BSD or a Free Software license like GPL. Godot fits this criteria, but things like Unity or UE4 don't.

Other options would be things like Ogre or Urho. They might be harder to get up-and-running than a more user-friendly engine like Unity or Godot but it might be worth it in the long run.

I'm ok with *GPL, but i should point out that they are explicitly incompatible with Unreal Engine[1]. I'm strongly against UE though, particularly due to its restrictive license.

While it's possible to obtain the source for UE4, you can't redistribute it freely, which means that we couldn't make this game properly open source. Unity has the same problem.

If we're going to make an open source game then our foundation also needs to be open source, meaning either we roll our own engine or use something like Godot or Ogre.

They're improving the renderer a lot for their next release. They have some screenshots here and here.

As for performance, see my post (as well as the first of those blog posts) for a discussion of C# support and GDNative (seems I misremembered its name).
