Did you start with the original Yakuza? Kiwami has a couple things that would feel odd to a newcomer if they don't play 0, and the only reason you're skipping Majima Saga here until later is because you moved 0. If you start with 0 then all the context needed for Kiwami 1's additions and Majima Saga are available.
Plus, to be fair, we have had a massive number of newcomers credit to 0. It's probably the favorite in the series now.
