Yes it is a little bit scary., but nothing more. The torch requires constantly new batteries and without them you can not kill the ghosts so easily and ammo is never enough. 3-6 enemies appear in the forrest from nowhere at once and that sucks... cos the torch batteries do not last even 30 seconds...
It though that the pc-version of this masterpiece was lost forever! I own the PSX-Version too, but the pc-version has of course better visuals... similar to the bleemcast port. I`m running it on a i7 3770, Win7 64 and 1080GTX without any problem. The only thing is that it does not start with the GOG-starter instantly so I have to launch it directly with the original .exe, maybe a reinstall would help... gotta check it later. The special VR-Missions are also includend and it works very good with a XboxOne Controller via usb-connection with preconfigured buttons to the original PSX button layout. Dont think, just get it and and enjoy one of the best video-games Kojima has ever created.
