I had the exact same impression but they had a long string of remasters to churn out for PC. Gaiden is more like a standalone expansion but swings like a main installment in content.
I am very curious to see how the release schedule changes with devs moving into full blown top seller JRPGs instead of story focused beat-em-ups.
The canon series order is basically:
Yakuza 0
Yakuza Kiwami 1 and 2
Yakuza 3-6
Like a Dragon
Like a Dragon Gaiden
Like a Dragon Infinite Wealth
But fuck SEGAs shitty DLC practices, I buy Yakuza games at half price or less as a personal rule.
I mean billions of people believe in magic sky man, another few billion believe in magic sky man’s father, and the last couple billion believe in magic sky man’s brother
…and are all convinced their magic sky man is real and the others aren’t, so…
