The syndicate division has been around a long time now and has no bearing on the game, how about making it do something. One idea could be to adapt the current weekly XP reward based on syndicate daily gamer points. E.g if syndicate is set to traditional then instead of weekly reward of XP then they would get cash instead, maybe up to a maximum of 20 * City income. so someone on 20 billion city income would earn a max of 400 billion depending on sydnicate daily GP. if syndicate is modern then they continue to get xp as a reward
