You know, it suck that these 4 don't work with each other at any point in the game (As in, all 4 of them)

Na, Dead Souls quality as a game had nothing to do with why it didn't do great in the west, in japan it's sales actually weren't that much lower then Yakuza 4's, but in the west It was just the wrong game at the wrong time. The market was flooded with Zombie games, so Dead Souls was just another drop in the bucket. Aside from Yakuza 1 being a million seller on the PS2, the series didn't top a million sales again until Yakuza 0.

Maybe it was due to the series being limited to Playstation only that it didn't get as much exposure as it could have, since once Zero came out and then it came to PC then later Xbox the series has been doing WAY better. I know I saw a review for Dead Souls back in the day, and the game really interested me, but I didn't have a PS3 at the time I would have totally bought it if it as my First Yakuza game if it was on 360, I only bought many years later digitally on PS3 once I had gotten one.
