Yes it's a good idea for an AC collector to try and limit what they collect at least at first
I would say start with all retail items of what you have listed
As there are some statues, guides etc. that were press or ubisoft employees only
Also I think you mean ACB (Assassin's Creed Brotherhood) Codex Edition
UK had ACIII Freedom Edition and ACIII Join or Die Edition
Maybe ACIII ubiworkshop edition too
