So here I am, fallen headfirst in the botomless barrel.
Chaos, Battle of Wizards was hands down my favourite game all through that one summer. I could play it for hours. I did play it for hours.
In short it goes something like this : There's a table shared by a number of wizards. There's a cast round and a movement round, and then another cast round and another movement round. You get a little spell list and you pick from there every turn, they have difficulties which impact your chance of success. Spellscan be either lawful, chaotic or neutral. If you cast lawful spells you become more and more lawful making subsequent spells easier. If you're lawful and cast a chaotic spell you become less lawful (eventually go through 0 and start being chaotic).
Castwise you can summon various animals such as Dragons, Leeches, Liches, Centaurs, Ogres and whatnot as well as the undead. Only the undead can attack the undead. Some creatures fly and some crawl, some even shoot. Summoned creatures can be cast as illusions, which ensures 100% success rate but also makes them vulnerable to Disbelieve, a spell all wizards have in abundance. Also castwise you can invoke direct damage spells, such as Lightning, you can create castles, forests, you can give your guy wings and bows and armors. Finally there's flames and globs, which spread each turn.
In the moving phase you can move your various summons, climb on top of them, climb into a tree, go into a castle and so forth.
The trees are my magic forest, I'm into one of the trees so not visible. The red guy brandishing a longer left arm is my ogre, going one square a turn towards that unfortunate bottom left wizard. Up top the green straw is what my wraith left out of an eagle. It's now headed towards the upleft wizard. There's a castle there, and the goop slowly spreading.
And in the end, of course,
Ps. Almost forgot : Myke Black has it up (Flash remake) on his site, among other things.
