One thing that has always bothered me about Col1 is that the War of Independence is very anti-climactic. This should be the great final point, the most difficult and exiting part of the game!
A big part of the problem is, that the REF forces are defeated too easily. Despite their superior strength, their forces are quickly destroyed because,
a) the terrain penalty
b) they cannot be rearmed after defeat, like the player's forces
- Keep a), but make the AI aware of it. Make the REF choose open ground whenever possible
- Demote defeated regulars to unarmed regulars. These are only destroyed when defeated once more. Allow them to be rearmed (and mounted) in REF-controlled cities
- Give the REF muskets and horses (or money to buy horses and muskets) in Europe every round. REF ships can then pick up these supplies and bring them to REF controlled cities in order to re-arm and mount units or arm the citizens for even further strength. The amount of horses/muskets/money supplied each round should depend upon the difficulty level (e.g. set to zero on easiest level but give 100 horses & muskets per turn on most difficult).
- Allow the REF to land multiple places, thereby also forcing the player to defend multiple locations (e.g. one main landing, but keep some extra forces to attack weakly defended positions away from the main battlefield).
