✦ AI summary

AI: The Somnium Files is a mystery visual novel that players praise for its engaging investigation mechanics, memorable characters, and clear passion project feel reminiscent of Ace Attorney, though with a notably quirky and eclectic tone that won't appeal to everyone. Common complaints center on the occasional action sequences breaking up the investigation flow and the game's heavy anime sensibilities, which newcomers to the genre may find off-putting or cringeworthy. Players familiar with Spike Chunsoft's work or DS-era visual novels seem most likely to find it a worthwhile experience.

Well this was just a delight. Felt like playing Ace Attorney for the first time again, except much dumber and hornier, for better and worse (not fond of the action sequences to be honest). A really good mystery game with (mostly) very enjoyable characters and unique mechanics during the Somnium segments to set it apart from the rest of mystery VNs that oozes heart from every disgusting little empty eye socket it has. Sometimes you play something and can just so clearly feel it was a passion project that came into being, and this is one such case. I would not recommend this to anybody who isn't familiar with DS era visual novels or other Spike Chunsoft works because of the... tone, let's just say. I think this would overdose most newcomers in anime ♥♥♥♥♥♥♥♥, but if you dig games like Ghost Trick, the aforementioned Ace Attorney series, Danganronpa, or Zero Escape, you're gonna like what's essentially all of them thrown into a blender with a cherry on top. Also, strong contender for best bonus feature you unlock in a game after beating it. And credits sequence. Uchikoshi is my favorite Californian girl. That being said, Kagami didn't get his secret ending with Date so maybe the …
