Wow, loaded up this one last night, what a sweet game. Fantasy this time instead of historical based. I remember some of here has some great games on Rise of Nations at those LAN thingies we do time to time.

Only problem is, I don't recommend installing this one at 11:45PM when you have to work the next day!
Lots of fun eh? Have to bring it to Fraga ;)
