Without trying to compromise the integrity of our individual lists and what they mean to us, what can we do to avoid splitting the Yakuza vote 6 ways?
Like, let's say you were only going to choose ONE and only one Yakuza game to allow space for another 14 games on your list, which game would you choose?
For me it's very easily Yakuza 0 and that's the one I suggest we back up IF you're only going to choose one Yakuza game.
Tangent: as someone who put all games from multiple franchises in their list (i.e. not doing a "one per series" rule), I can't help but comment here. In the quest to solve one issue (caring about whether too many IPs are falling below the arbitrary threshold of "top 20"), I think people are creating another one by doing "one per series".
Or rather, there's always a trade off, with no way being best. Do you want your list to be an accurate personal ranking? Do you want your list to be a public form of self-expression ("here's the variety of games I felt were best")? Do you want your list to be a strategic vote in order to influence the final result? ("I know X is hugely popular and Y has no chance, so...")
Incidentally, the best theoretical solution to path you are taking is to have everyone submit some kind of list of Yakuza games, either ordered from best to worst or with their personal, subjective scores. Then you can choose a voting algorithm to find the best 1 or 2 candidates, and let everyone know.
An interesting question is: what's the best voting system that would decrease people's desire to do "one per series" in the first place?
