Thanks! I was actually going to make an algorithm to find all the possible variations, but I realised that the additional options were limited and immediately obvious, and hard coding them would give me more control of game balance.

The blog is really about sharing ideas, so yes "forcing" the read is part of it XD - hopefully some ventured into the rest of the blog, which is more "saving the world" sort of material. I really appreciate your comments here, I wish I'd found them straight away :)
