SKU, Price Point.... I always hated the corpo speak of the glorified bloggers.
That said I much prefer the situation in 2022, when you can actually buy the games that you want to buy for nearly any platform even if the remasters can be overpriced.
These cats have clearly not lived through the days of PAL and region locking. Many games were practically impossible to find unless they were reprinted in an uglier 'players choice' form or published by European distributors like Ubisoft.
European release often meant just 'UK release' too for games from Namco Bandai, Konami and Square Enix. So you had to be lucky to have a store around that sold imports and those weren't the German or French versions.
Many games were not available on the release date either because toy stores that sold them didn't give a shit about video games and when they did get them, it was like 1 copy.
And when Nintendo teamed up with those folks for European releases they would print 3 copies of Dragon Quest DS and 4 million of Yoshi Touch 'n Go.
Some of the boxes of these games I've seen in person only once in my life and I will probably never see them again.
And that was for 'current gen' games. Once a new system was out it became impossible to find anything specific for your previous machine.
They would always have 200 copies of Rayman, FIFA and Need for Speed but good luck finding a Castlevania or Metroid GBA game.
You just had to be lucky that at some point they tossed a box of left-over games from storage in the bargain bin and in between a sea of MyLittlePony you'd find a gem.
