Took me a while to realize this thread was in HR now. I guess that’s cool, anything goes here I suppose haha. Still my first big suggestion is to be consistent with what constitutes a Re-Issue/Re-Print vs a new "Edition’ (or if there is even a worthwhile distinction there) vs an entirely new game which properly should get a new Title.
For me this boils down to whether or not the update/revision can be handled by just updating the manual (e.g. the rules, or the set up cards) vs requiring major changes to other contents inside the box.
If the map does change (beyond cosmetics) like adding new territories and new sea zones, or adjusted connections/boundaries, that’s a new game and it should have a new name. If entirely new unit sculpts are added, that game should get a new title to reflect this, since it’s a very big change. Basically anything that breaks backwards compatibility with an already existing board, or which makes a previous release of that board obsolete.
You know what I mean, like if all I have to do is download a pdf of the new manual with new tech rules that’s one thing, but if I’m required to have a new map and new sculpts that’s a rather different thing. If the only changes are to the rules for existing stuff, or new unit set up cards for existing stuff, or if the changes to the map are only cosmetic, (like a new look and feel, but otherwise all the same TTs/connections) then that release should be a new “Edition” of the previous game’s same name.
Sadly these conventions have not been very consistent in the past, and so I think there is a fair bit of confusion regarding the whole ‘which edition?’ thing. This is part of the reason why I think they should drop the concept of editions for anything which should properly be considered sequels and instead give those new titles. I would look to the conventions adopted in Book publishing for guidance here. If the manual is being re-iussed, and only that, then a 2nd or 3rd edition printing under the same Name makes sense to me. If it goes much beyond that, then it should get a new Title/subtitle, or else some qualifier there like “Revised” or “Advanced” or “Anniversary” or some season/year whatever, to make that really obvious. I think anyway, but I’m pretty sure that ship has sailed already hehe.
