夢現Re:Master
I didn't like Saki's route as I was reading it, but having finished the rest of the game I can now say it was far and away the best. Despite finding it very long and repetitive, it was the only route that took the game creation theme seriously. I was also severely disappointed by the twist in Kokoro's route - I don't like it when a work that's been grounded in reality the whole time suddenly takes a turn into the supernatural.

P.S. props to the voice actors and scenario writers for pulling off some uncomfortably realistic verbal arguments and nearly giving me an ulcer every time Saki and Kokoro were on screen and this theme started playing

A creator-focused work about making games that actually sticks to the theme! Did an excellent job of filling the saekano-shaped hole in my heart, to the extent that I actually purchased a physical copy of the game. Very funny and filled with lots of anecdotes about the industry. I've tried a couple of Romeo's works over the years but this is the first one I've actually enjoyed - I understand a bit of the hype now. Teruha's route was definitely the best, though Kuroda was my favourite character. I also want to check out the anime adaptation at some point.

Unfortunately it doesn't run at all on Windows 11, so I had to download a Windows 7 emulator and install it there.
