there are a few things that prevent me from playing C1. For example formations. There were buggy. If you click move there and attack everything on its way, well once the attacked one time the formation stop moving. While the were mandatory at the beginning, nobody used them later, due to weak boni but especially due to being bugged. I dont care for the better graphics in C3, I dont care for balanced units (since I can do that with the modkit as well), but I do want and need better AI and a bug free game (no auto-stoping).
