I have not had any problems running this game other then the random crashes, until this map, it was called Itellya or something like that I was me vs lord relias or whatever his name is, I was playing and my game started getting slower and slower, first I thought it was because i noticed the computer was making companys and companys of the most useless units in the game and spam attacking me, which was fine because I had company's of overpowered archers to defend me, anyway I got sick of the lag and attacks so I decided to annihilate him, as I went north and started destroying his city's I noticed it had citys stacked all over the place, there was 3 literally connected together and as I'm not aloud to build city's close together, I don't know if the AI can get around this, but the lag kept getting worse, as I continued using my ninja archers to rape the countryside I kept noticing that it had placed city after city practically covering the map, until it got to the point where the game just crashed "out of memory" which is understandable the computers portion of the map was just city's spammed.
