I recall finding this game a ways back. I had stumbled upon the words worth anime and found out there was a game. I had so many issues getting it to work. It would crash repeatedly during gameplay unless you turned off the 3D acceleration. I recall getting it to work in a Virtual Machine with 3D acceleration and played through most of it. Recently, I had a desire to do so again, but didn't want to use a VM. I've been moving over to Linux recently. I always wanted to get away from Microsoft and Apple, but being a gamer it's been difficult. Finally, Linux has matured enough with things like wine, proton, GPU passthrough, and Lutris. After playing around with softwares like cdemu to mount the iso disc, installing it with wine, adding codec pacs via winetricks, and adding a japanese language via winetricks I finally got it working. The Xbox controller even works in wine. This is the first time I've been able to play through it without a Virtual Machine.
At any rate, the aretwork is quite nice for the time period it was made. The combat is okay, but nothing great. It's mostly button smashing. I enjoy the story and diaolgue. It's not a bad game as adult games from 1999 go. I kind of like the Anime better, but it's still a fun game. It's too bad that it didn't catch on more. It's also too bad that it relies on things like cinepak or indeo video that thankfully can be installed via winetricks. This would have been a good candidate for official translation. I really like the horseman. He's such a horny bastard. I would recommend it if you can get it working. As of yet, no one has really made a good XP emulator, but wine and proton mostly do the job thankfully. Otherwise all of those old games that are pretty fun would be lost to time.
In case you intersted, I'm using Arch Linux with KDE Plasma Wayland. It's not the easiest Linux to install, but once it's up and running with a GUI environment it's fairly simple to use. You just have to get the hang of how to install software and configure thngs in LInux. Most of the software you need can be installed with the pacman utility that downloads it from a repository. That's how I installed wine, winetricks, and cdemu. There's an archinstaller you can run from the live CD that makes installation easier. If you want something more simple I would go with Ubuntu or OpenSUSE, but I've found both to be a bit more buggy. You should be able to install all the same software and run the game though. LInux is Linux afterall. They basically use the same kernel.
