Got around to playing all the Arcade games in Pirate Yakuza, and it made me realize the arcade division of SEGA is vastly underrated and overlooked in the west, since console games were what caught people's attention.
SpikeOut most of all is the most fascinating game Available this time, It was in Infinite Wealth as well, but I didn't end up playing it there. Seeing SpikeOut in action is finally the last bit of history I needed to give the proper take in regard to the Yakuza and Shenmue comparison. The take that "Yakuza is just Shenmue but better" has always been a shit one that only cares about surface level Similarities. The reality is that Shenmue and Yakuza have almost nothing in common, on a game design level.
Shenmue is what if Virtua Fighter was an Story focused Adventure game with Simulation elements. Yakuza is what if SpikeOut was a JRPG. There is a ton of Virtua Fighter DNA in Shenmue which is obvious enough, and when you play SpikeOut it's just as obvious that Yakuza has a ton of SpikeOut's DNA in it's design. Yakuza doesn't just heavily reused it's own assets, it's still reusing assets from SpikeOut, I've spotted some animations that got carried over into the Yakuza game, on top of game design elements. All the Long battles in Yakuza have SpikeOut's level design as their origin. Even the idea of a little kid following around the tough adult trope that is Haruka and Kiyru, which Pirate Yakuza revists with Noah and Majima, that was in SpikeOut first, with the main guy being Spike, going around beating the crap out of dudes with his son Spike Jr alongside him.
But bottom line SpikeOut kicks ass, and still worth playing. I got to checkout SpikeOut Battle Street on the OG Xbox since that's a sequel staring a grown up Spike Jr, they also made a spin-off SlashOut that's a fantasy game with the same mechanics.
