Memory usage of the game, when loaded.
I have watched it with Process Explorer.
When the RAM usage reaches approximately 2 Megabytes - it crashes.
This also is the maximum of an "signed 32 bit integer".
The game is 32 bit, but some programming statement is using a Signed Integer for some purpose when it should be using an unsigned integer.
Even if this and all other similar issues were found the game would max out at near 4 Megabytes of usage.
If you are playing online with others, this would make you out of luck.
If you are playing solo with computer opponents, sometimes you can save a game, say every 5 minutes (with a different name for each game) - and you can load an earlier game. When you succeed, the just-loaded-game will often use much less RAM (and then slowly grow).
This also has some downfalls as the parts of the program that Load and Save the game have issues. Loading a game beyond a certain complexity will fail, usually with error "FAF ran out of local 'stack' space during load"
