I've "completed" my first simple age. I spent 1-2 weeks on it. It's called Lohdehvis, a minimalist homage, designed to run well on my 2001 laptop. Mostly puzzles. I didn't do any baking, etc. so if anyone wants to run with it as a foundation (re-light/lightmap, re-texture, re-model) I can send da blend. Cyan's music happened to be almost exactly what I was looking for, but if anyone wanted to make something original, you could use that track (dsntRestArea) as a guide with some Elliott Smith/Sigur Ros/Ancient Egyptian thrown in, or do whatever you felt like.
Thanks for the tools & tutorials. This was fun.
