1. the community is so divided and separated that i dont think you could really promote a strongest game. everyone has their favorites and some people even hate certain ac games. id recommend running AC4 and onwards because online is much easier to set up than kai or something else. iirc AC4 servers are only up and running for 360 side and have been shut down for PS3 2. ac4 was better balanced than FA for a long time and overall the game takes more skill. FA got balanced decently with its latest patch, but everyone completely lost interest by the time it came around and now FA has a terrible stigma for being trash. also, some people like to feel old so theyll always tell you that the older games are better than the newer ones 3. later gen games dont have many tournament standards as far as ban consensus and stuff since nothing is really worth banning in current versions (AC4 blades matches should ban parry blades though). rules for AC4 are generally BO3 5min/ea and restricted to 2-3 maps. other rules like winner/loser AC switching should be considered but last tournament i saw, they had no restriction on AC switching. i prefer that winner cant swap ACs but loser can good luck with starting a solid community tho. ur gonna need a whole lot of magic to pull it off
