I had not, taking a look at it now. Project Redshift already has its core systems like movement, combat, space flight, and crafting all documented or in development. But since I think there are smarter people than me who have toyed with space text-based games in the last 20 years. I try and check out any scifi oriented ones I can see. Find out if they came up with an elegant solution to something we might be struggling with.
That and it's just fun to see what's out there already and what features haven't been supported prior to Project Redshift's development.
