This is an interesting twist on the usual LitRPG genre - this time the protagonist isn't an almighty hero running around being all smart and glorious; instead, he acts as a director, manager, trader, diplomat.
Don't get me wrong: it still kinda is a power fantasy. Except Charles' feel-good exploits are centered on capitalism, instead of a sword or a gun. (Interestingly, I don't think there were any 'exploits' in the traditional gaming sense of the word - using bugs or unintended feature interactions to get an advantage.)
The book was enjoyable enough; a typical "not great, not terrible, you get what it says on the tin" situation. But sometimes the prose was befouled by corpo-speak in unexpected places. For example, we are unironically presented a fantasy-medieval peasant woman saying things such as "You’re promoting people [and] you’re giving us the tools we need for success". 🙄
