In the year before UE4’s public launch, we spent a lot of time considering whether there should be some sort of amateur/pro split in the Unreal Engine 4 tools. Ultimately, we concluded there wasn’t any split that would be widely satisfactory. The whole spectrum of UE4 features is used by at least some developers of all size levels, for example with some small games and mods having high-end graphics, or requiring C++ source, or otherwise. So, a UE4 Indie / Mod Edition would leave a great many indies and modders unsatisfied; though most of them wouldn’t require most of the missing features, each of them would be hampered by one or more of the missing features. Plus, we’d hate to fragment the community.
