Ive 2 Ideas for the formations: 1. Babarians schouldn't can make such nice formations as the romans. So my Idea is that every unit has a value which says how good the unit can go into a formation. Ive thought of a value between 0 and 5. A value of 0 means that the unit isnt able to go into a formation (the unit simply goes to a random point near the target), a value of 5 means that the unit will exactly match the formation (the unit will go exactly in that way to the target that the formation wont change). The higher the value is, the less randomly will the movment be. (3-doesnt match the exact formation, but a formation alike) 2. Formation Boni: That some units have some special formations which give them bonis. The phalanx for example could have a formation in which they can hardly move but have a big bonus against riders (and a small against any other units).
