Hey, I appreciate your answer!
You pretty much identified the role I had in the previous game jams so far. Unfortunately, I have also done programming, which resulted in me being split into too many domains.
The advice you gave pretty much sums up my experience and conclusions. I am always striving for a minimum viable product, while at the same time leaving place for further improvements if it is plausible. I do agree with all your points and how you triaged the planning.
I would love to work on other major engines such as Unity or Godot, however, up until now I've been the main pillar of the teams I've been working with and I'm worried that with an engine that I am not familiar with I won't be as useful as with Unreal. :)
Right now, I don't feel like leading a team for a game jam, so this time I am not gathering one - just hoping to help some people with their projects. If you're interested in jamming together, hit me up at Discord: Melchior#9248
