I've decided that the M.A.U. Invasion game will be in a number of game-formats, from the computer game (I'm still hoping to have a playable working level demo by the end of August) to boardgames and card games. I might make a computer version of the card games as well at some point.
Making the card game also gave me lots of new ideas for features in my computer game. One of my favourite cards is the STOMP card that lets an M.A.U. step on infantry, in addition to any weapon attacks that turn. I think I'll definitely add that to the game, so M.A.U.'s can walk through squares where infantry are, and the infantry are squished :) Of course, people's infantry should be inside an APC when they're outside buildings, on the battlefield. Perhaps I should let Heavy M.A.U.'s squish little vehicles too :)
Anyhow, the next week or so I won't be working much on any of my games, as I'm moving house. I tend to get rather unorganised when moving all my stuff to a new place :)
