After finding solutions to some technical things I've returned to creating content or more like trying to get things playable. It feels a bit weird, yet nice. At the moment I'm working on character creation which involves some RPG system design as well, with skills in particular.
The RPG system is going to focus on gear and skills, not in experience because there is none except in skills (as a limited way to advance). I never liked experience based systems myself so this is an attempt to try something different. I guess you could look at getting better gear as "experience" of sort.
I feel like the technical solutions I've reached are not going to change this time, for real. At least not in a dramatic way like before.
