Is there a limit on units?

[Archangel]

It seems I have exceeded the maximum allowance of units in my scenario. What exactly is the limit, and is there any way I can set it higher?

[DarthVeda]

Yes, I believe there is

For cities, it is 255

For units, it is either

1785, 2040, 16384, or 32768

[Archangel]

Any way I can change it?

[DarthVeda]

Unfortunately, no.

Because Civ2 was written for Win 3.1 computers running DOS as their basic platform, much of its code still has basic memory limitations put on it. Even if you could increase the number of units the game allows, the game would probably crash or perform unpredictably.
