Unlike my previous retro gaming posts on Doom and Re-Volt, Thief II: The Metal Age is not one I have played when it first came out, we can be sure therefore, that my opinions on it are not tinted with rose coloured spectacles.
Thief II the Metal Age has just been re-released on Good Old Games.com, along with the first in the series “The Dark Project” I thought now was as good a time as any to give it a go. GOG do ensure that any games they sell will work on a modern computer and operating system before they sell them, even if it means shipping them with DOSBox, we can however do better as both games have received fan patches that mean they don’t just run, but run in resolutions suitable for a modern monitor without letterboxing and upscaling. The GOG forums have all the information you need, for the first game you need to go here and for the second have a look at this. Note that for the first one there is an additional step to get the briefing videos to work which can be found in the second post of the thread.
