I'm mainly scipter and not far with things like model design.
Focus on one game -> yeasterday I shared games with some classmates and asked to say what was the best. Most of votes were for MiniPH, because there aren't many games of this type (especialy small and free). It's easy to expand and I can improve design, but ODE stops me here. I'm not sure that engine with changed built-in ph's will be released till contest end and I'm twice unsure that updated LiteC free will be released...
So normaly I have a one WIP project of every type and expanding depends on mood.
I have other 4 games finished in script, but lacking when it comes to level design.
