The aggressivness parameter tells the unit(s) how active they can be when engaging an enemy. A low aggression unit will be more likely to bypass or run away when engaged in combat, while a high aggression unit will be more likely to fight and fight hard. Another key feature of the Aggro scale is that when set to max, the commander will push all his units into the battle and leave little or no reinforcements. For example, a normal attack with a battalion of 3 companies will have 2 companies making the attack while the 3rd is used as a reserve unit. Setting the aggro to max will have all 3 companies in the attack with no reserve.
The formation settings apply to all units as a whole. If you have 1 battalion and order it a formation with a width of 600 meters, the commander will spread all his forces units to cover the 600 meters.
Matrix games are definitely overpriced for too long. It's been 4 years since
Highway came out and it still sells at full price from their website. I picked up my copy from gogamer.com for $20, although I don't think they ship to Europe.
Check out EBay, most people there ship worldwide, and it'll be a lot cheaper than 40 euros.
