I *loved* AA back in the day, before the medics and SF stuff came into the game and (IMO) ruined it.
Insurgent Camp and the map with the bridge were both my favourite maps, although a few others had merit too. The honor system was great for weeding out people who didn't want to play seriously and overall it was just about the most fun online experience of the time.
Must be getting on for 10 years ago now?
