After playing for a week, I quit and went back to other games. I mainly don't want to play Troy because of some battle problems. The campaign is great though but some buildings, like Paris's Helen chain, feel useless or are bugged, like the wood archer ammunition chain.
For battles, I hope they'll fix unit collision and chariots. Obviously chariots are a problem as seen by the multiple posts. But there's another problem where, in battles, if you have a mass brawl and one unit retreats/routs. All the units tasked to attack that unit will pull through to chase and get instantly shredded by the enemy. This seems to only happen to the player's units as the AI has near-infinite apm and they'll redirect their units to attack the unit that pulls through to chase.
Charges seem to be really hit or miss too, they either seem really f'ing weak sometimes or are perfect. I guess it's the difference between light/heavy, or just collision problem again.
Also, with ranged units, they seem to really take forever when you command them to attack an enemy unit. If the unit is to their side, the whole archer unit will take like 5 seconds to turn 90 degrees, pause for 5 seconds, then adjust again doing god knows what for another 5 seconds before firing, instead of just turning each body 90 degrees and firing. The ranged units feel really static, this isn't a problem for some battles. But in battles where it's really messy with units sprawled out everywhere, or battles where speed is important, it's really frustrating.
