I really like this game and I still have my old LucasArts CDs, which don't work well out of the box on Windows 10. This GOG port does work on Windows 10, but, as usual from GOG, translations are gone (English only, although my CDs have the French version), and HiDPI support has issues (whenever you're saving, loading, or changing an option, your screen flickers and you go back to the Windows desktop for a fraction of a second, so this happens dozens of times while playing). It's nice to discover the soundtrack while playing the game now, though; that part never worked on my old CD version. So: a nice port if you don't care about the translations or if you don't have an HiDPI setup. Otherwise, keep your old CDs inside a Windows XP VM.
Telltale Games from that period were mostly uninspired, in my opinion. They had good licences, huge potential, but character development was often embarrassing (except for some Sam & Max episodes, here and there). Dated graphics (back then), unmoving stories, and worst of all: almost every character is a cliché. No depth. Don't expect LucasArts-type characters, it's just going to be Humongous-type characters -- except that it's targeted at older players. Storytelling could have been so much, much better from a studio whose name is Telltale. Anyway… I could still recommend it if you're NOT looking for strong storytelling, but the humor ain't that good here, and the puzzles are just okay. It's just nice to see the Delorean again. Moreover, GOG doesn't ship, as of 2018, the macOS version that Steam has, so well…
This is an affordable way to get the excellent FM-TOWNS version of this game, which is a really good job. However, please note that the audio is just provided as 128 kbps MP3s. The original audio could have been provided as FLAC files (at least as an option), because the original audio is lossless, but that's not the case here. And, although the original DOS version is provided as well, the original translations are missing. So it could have been a better job, GOG...
