Just thought, for those who are interested and remember the original game over 25 years ago, there's a free online version of M.U.L.E. available now:
I've played only a little bit, but overall the game has aged relatively well and feeds the nostalgia genes in me.
If you've never played it, it's a great lunchtime pseudo-casual economic game about a bunch of different alien races competing to colonize a planet. It has potentially ruthless gameplay wrapped in a candy layer of cuteness.
