As an artist/designer, I don’t possess great programming skills, not do I have time to learn it all. One thing that always pushed me away from UDK was lack of complete game code included into package.
For example, while Doom 3 (idTech 4) engine is dated, it provides entire game logic code, out-of-box. All that has to be done is art. Literally, no programming is required to make Doom 3-like game with richer experience.
Does UE4 come with a complete and working game logic code that can be used as solid base for a single player FPS game ? (inventory, ammo, weapons, non-weapon gadgets, AI, NPCs, etc.)
