There was no issue board, no concept, no plan what the game should look like. Needles to say that spaghetti code gets a whole new meening. Instead of writing code you connect function blocks with execution lines. 'It works, so it's good enough right?' On top of that UE4 has a visual scripting system called Blueprint. The others were all modders who somehow got their shit working. Well, it turned out I was the only one with a professional programming background (this is where I should have run). I wanted to learn UE4 anyway and the other members have made many mods before, so I joined in.
One day another modder wanted to make his own game using Unreal Engine 4. 4y I have been creating mods for Skyrim and Fallout for a few years now.
