old school battle isle, completed it
Im just playing enemy within, but its very similar unknown so I think I should have done long war
Battle Isle 2 is one of my all time favourite games, and is never uninstalled

In fact I'm currently trying to disassemble it (aka bashing my head against a brick wall), to give the AI a bit of a helping hand

Aside from the cheesy ways you can make the AI do stupid things, BI2 is amazing fun. Sadly the AI by default is dumb, relying on overwhelming numbers to present any kind of challenge.
