1. Does anyone have experience of ultra-large maps?
Played a few with a buddy. The hardest part is balance, may find halfway through the game that city placement was all out of whack.
2. Does the game simply crash?
Only once in the 2 years ive had the game.
3. Does the AI just sit in its trenches and wait to be attacked?
Nope, it throws hordes and hordes of stuff at you, usually with no XP or supply.
Once it gets those things going it can be pretty devious.
4. Does the AI make strategically stupid decisions or tactically stupid decisions?
I would say strategically more so than tactically, it never seems to put units into a position thats just begging for an encirclement, but then again, it makes divisions with 167 rifle men, 1 machine gun, 1 mortar, and 2 trucks...
5. Is it still fun?
Immensely if you have the time and patience to see it through to the end, if you ever manage to get a balanced game that isnt over as soon as you eclipse the AIs production numbers
Really the issue, is that the AI throws hordes of shat troops at you, and you can sit there, entrenched, letting the AI hordes wash over you, and then start your offensive against the AI with an entire army of 99 XP divisions.
Light tank IIs, when the AI has no medium tanks or atgs, with 99 xp, can slaughter literally thousands of rifle and smg men and never even take a readiness hit. Its pretty funny really.
