The game is a classic and everyone will know about it by this point. It had its 25th birthday recently so I gave it a go after more than a decade. Gog claims its part of the "Preservation Program", but while it launches nicely, it's way too dark, which needs be fixed with community mods, and I read everywhere that I should update the map files because the GOTY got an older version back in the day. No idea if this is fixed in the GOG version or if I have to do this too. That's why I'm only giving 3 stars, my GOG Deus Ex Experience is not great. It seems the only change they made is to make gog launcher pop up when you launch the game.
