Definitely Age Of Empires II. I played it 24/7 and I did it all, missions, multiplayer games, all of them... And then I got the cheats, and I ruled, at the game. And then I stopped playing because even the PC could not beat me at Extra Hard. Lol, my story with AOE, Misa Misa
Zelda, any of them, is my favorite strategic game. I like the old Zelda the most though (Ocarina of time), it never gets old for me.
Board Games: Diplomacy Axis & Allies Risk Video Games: Rail Tycoon II (I still play that damn game a lot even though it's almost 10 years old) Simcity 3000
24/7 wow.. I have no patience for that game, I think it takes too long to build up your civilization and fight the enemy. I always used cheats to hasten it up but cheating takes out the fun on games Warcraft then now Dota Red alert Generals love RPG's and FPS too...
