I'm all for simple games concepts, and Chaos, the Battle of Wizards has one of the simplest yet. To summarise, take a black square (eg a burnt field), and stick in it a number of wizards, between say 2 and 8. Give each wizard different ratings for attack, defence, you know, all the usual Games Workshop sort of stuff. On top of all this, each wizard has a number of spells with which to destroy all the other wizards. That is it.
Since as I am as good at games as a deranged goat, I like games that make it easy, and Chaos is very easy to play. You cycle through a couple of menus to select your spell and when told to move your character(s) just position the cursor over the piece you wish to move and move it. Why characters? Some of the spells allow you to create magical and mythical beasts, like manticores end gryphons, to aid you in your fight.
To put it simply, Chaos is great. It's colourful, it's very easy to play, and above all it's probably the most fun you've had since you pickled your granny.
