Reincarnated as an Imperial Prince by SorryImJustDiamond

Thrue

Don't believe the historical and modern knowledge tags 100%, because with it's SUPER unrealistic scenarios this WN should have a [fantasy tag].

So if you only want entertainment, please don't be like me who forgot to turn off his brain.

Happy reading.

I find this review by Nothing6468 from webnovel quite good

The is basically a kid friendly kingdom building novel with no political intrigue or conflict. All the changes he does have no repercussions, conflict, and passes too easily. He introduces modern weaponry without any safeguard to espionage (he increases the budget for internal security and that’s all he did) but nothing gets leaked or stolen. It would had been better to introduce conflict when designs get stolen. He signs modern reform bills left and right like free education and agriculture reforms like he has infinite money and no concerns. There should had been more though put into this or rolled out progressively instead of all at once. There is no political backlash from the conservative faction (if they exist at all) from all the modern reforms rapidly being introduced. The romance feels like a middle school kiss and get pregnant love and very forced and rushed. The new queen is an innocent trophy wife with no character and introduces no drama or plot additions. He also allows her to choose if she wants to reject a political marriage between monarchs and the most advanced nation like it’s a middle school girlfriend breakup. It would had been better if she was a princess of an enemy nation or eastern countries so you have a vehicle to naturally move the plot to other countries with some drama and conflict. Also the pacing between the introduction of the terrorist attacks with the next reattempt is too long and readers don’t care about the terrorist group that killed the parents anymore. Add some conflict and don’t play it too safe.

This novel is a big bag of meh. 3 stars is an apt score.

May not be the best novel I've read, but certainly an entertaining novel. The only problem was the cringe and awkward English and conversation of the character at the early chapter; but as I am a frequent visitor in mtl sites, I can at least bear that much. Not to mention, it had improved later on.
Also, I've seen the comments below which said that the novel don't have conflict and conspiracy, but that is entirely wrong. The conflict was still being brewed at earlier chapter (around chapter 100-150). The problem is, the novel had a light and soft narrative, so you can't feel the seriousness of the situation.

This guy is literally reincarnated in an alternative world of the beginning of the 20th century and the best thing he can think of to give to this world is fast food and multiculturalism. Like wtf is wrong with you??

This novel is soft AF, no conspiracy, no fight, just introducing one technology after another into the medieval world. Don't bother reading this shit.

Scrap my previous reviews.
This novel is shit.
