Right out the gate, Shakedown: Hawaii is a great but flawed game.
Mainly a callback to classic top-down GTA with a business management sim aspect added in. These two different gameplay formulas create a fun game loop but unfortunately both have flaws to 'em that hurt the overall experience.

The Classic GTA aspect is hurt by the controls (On mouse & keyboard), they just don't feel as refined as they should be making for some frustrating moments and there's no remap feature for some reason.
On the business sim side, while this aspect of the game is downright addicting there's not much too it outside of the dopamine rush of "rising numbers", eventually you hit a wall and it get tedious.

The story is a pretty amusing sass at modern culture and consumerism but mercifully the game doesn't take itself serious.
Ironically enough some of the "modernisms" depicted in this game have since then become outdated making it clear what time this game came out. Really the only truly bad thing about the plot is the ending, past the halfway point the plot starts to drag and than it just abruptly ends.

Overall, Shakedown: Hawaii is worth it, especially on sale.
