Game Shelver 99: I must organize my Steam Library and defend it against pirates with a shotgun

Note: The gameboxes are only blurred / pixelated on the store page, not within the game.
The year is 1999. You are the proud owner of a beautiful pc game store. You feel great satisfaction by organizing all your games meticulously into their designated spots. Gently sliding that last box into the shelf... mhhh....  But alas, what is that?! You hear a menacing pirate jingle and suddenly a software-pirate ship appears in your store! And they start looting your games and throwing everything around! This cannot stand. This will not stand! You whip out your trusty 12 gauge shotgun... and start issuing some DMCA takedowns.

Features
Organize and sort the games you own on Steam into the correct shelves

Procedural store layout and procedural categorization challenges based on your games collection, with multiple correct solutions for high replayability
Categorize by genre, by tags, by year, by developer, by title or by price

Play peaceful mode and focus purely on organizing, or shoot and destroy software-pirates that loot your store in waves and throw your organized games out of the shelves

Adjustable difficulty (number of games to shelve, extra slack on shelves, number of pirates, ...)

Improve your sorting skills with FPS-style power-ups (carry capacity, highlighting, auto-shelving, ...)

Single player or online co-op (up to 4 players) with a combined game collection (3 or 4 players highly recommended. Your friends might see THAT ONE game you own they are not supposed to. In a 3 or 4 player game you can always point and say it belongs to the other guy! Wait. Actually there is no pointing mechanic in the game. Dammit.)

Nostalgic, late 90s / early 00s retro vibes with modern, over the top effects and a satirical (subtle, I know) genre-blend:  Tidy-Up Cleaning Organizer First Person Shooter Wave Defense (let's add "Quantum AI Blockchain Simulator" for the clicks).
