Sorry m8, but I only have the one copy and I simply cannot part with it (my favorite computer game of all time, without a doubt).

The good news is, you can get Shogun Total War, Warlord Edition/Mongol Invasions for around $5-10 if you dig. I think a friend of mine got a copy from Amazon online within the last month for only $13.95. It's out there still, and it's cheap. Good luck in getting a copy.

MI has additional campaign scenarios that you may like (1530, 1550, 1580 and of course, the Mongol Invasion), Historical Battle campaigns (several series of related tactical battles), additional units, and a few adjustments that arguably improve aspects of singleplayer gameplay over Shogun (e.g. the elimination of the Hojo and Uesugi hordes that sometimes dominate the mid- to late-game in the original STW).

I'm going to withhold comment about original STW vs. STW/MI as far as multiplayer battles online go, as that is a subject that tends to evoke a cascade of differing opinions around here. I will say this though, most who still play online on the fakeservers use STW/MI, patched to version 1.02.

Some were tossing about the idea of playing some original STW battles online recently, so if that interests you, check the STW MP thread that's stickied at the top of this forum. I think I remember TosaInu saying he enjoys playing the original STW and is ready and willing to do so.
