As I am bored today (well, procrastinating and taking frequent breaks), I thought I'd broach a topic we've never discussed (I don't think): how to mark Martian Coasters (MCs) so that they are clearly associated with the Xeno Treehouse spectrum. This will become very relevant, I suspect, if the IGDC has MCs as a design requirement--even if not, there's already at least four games that are extensible to upwards of 8 (or 10) players where pyramid and coaster color are relevant. I am basically seeking a sort of poll/discussion about the "best" way to mark them: as obvious as possible without obfuscating the key coaster elements (arrows and squares). My Idea: I am thinking of using a Sharpie to make an X across the entire coaster, corner to corner, but drawn as if BEHIND the squares (it won't intersect any arrows). Thus, only the white portions of the coasters would show the X, but (I think) it will be glaringly obvious to spot this X and associate it with Xeno and, thus, focus on the arrow colors instead of the square colors. This idea is a derivative of my first idea: to make a thick X on just the center square and in each corner of the coaster. Thoughts? David
