Rat Simulator is a Digital Homicide style asset flip. The "developer" paid for/pirated a few Unity asset store assets, dumped them all in a blender, and submitted it to Valve as if they're real game developers.

Two notable criteria for what makes an asset flip instead of legitimate use of stock assets are whether those assets comprise the majority of the game, and whether the "developer" properly credited the people who created most of the assets in the game. This game fails both of those tests. The "developers" here didn't credit any of the artists and real, actual game developers who created the assets here, so this is plagiarism, as well as cash grab shovelware.

In this case, the asset flipper took a bunch of Unity Asset store assets and made a very simple third person "adventure" stealth game with rats. It comes across as a "bare minimum viable product". The idea that rats can swing open doors and pick up vases 5 times thier own weight and hurl them across the room shows that not a huge amount of effort or consideration went into actual rat simulation here. It has no value or merit as a real game.

The game assets are fairly mediocre/low quality which fits with the idea they weren't developed by the game creator... they look like they're "just reasonable enough" to go on sale as part of an asset pack. The issue of asset flipping aside, ultimately the quality of these assets is low and low quality always makes for a less than optimal gaming experience.

So, should you buy this asset flip? Is this better than any of the 100,000+ genuinely made games on Steam? Of course not!

Rat Simulator has the laughable price of around $8 USD, it's not worth it given the defects and shortcomings with the product, especially considering the sheer number of completely free, much higher quality games on Steam.

For comparison, the $8 asking price for this game could get you games like "Disco Elysium", "Doom Eternal" or "Stellaris". Quality, professionally made games like those are frequently on sale cheaper than this.
