Multiple movement systems in a module

[AmkG]

Caramel allows multiple wheels to be installed in a single module, and their bonuses add up.

However, this does not IMO seem to be good design. I think it would be better if size-6 Wheels has some advantage that two size-3 Wheels do not. This is because you can more easily sneak in two size-3 Wheels in various modules, versus a size-6 Wheels which requires 6 free slots on a single module.

My preferred solution would be:

• Higher-size movement systems have a small bonus. For example, a size 1 Overchargers gives 7% bonus, but a size 2 Overchargers gets 15%, size 3 gives 24%, size 4 gives 31%, etc.
  • Also scale up prices in proportion to the additional bonus larger sizes get, so that prices match the approximate power of the mecha.

Other alternatives would be:

• Weight discounts at higher sizes.
• Each module can have only up to one non-Overchargers movement system plus one Overchargers.
• Larger movement systems are cheaper: a size-6 Wheels would be cheaper than two size-3 Wheels.
  • Mildly undesirable since we use price as a proxy for effectiveness.

Logically, greater scale should make it easier to gain more benefits due to economies of scale.

Also, you can install Wheels on a Torso and it also gets added to the rolling thrust, so I cannot help but imagine that the wheels are on the ass of the mecha and the mecha has to squat on its ass-wheels to get its maximum rolling speed. Gotta wonder how wheels installed on the head work....

157 goes with weight discounts at higher levels. Size 21 and larger movement systems have the same base weight of 10.5 tons. It gives minimal increase in mobility, speed, and costs to existing mecha.
