I had Descent 2 in my life I've been playing it a lot since I was young it used to belong to my big brother but I pay him for that game and it's mine, Descent 2 works on my win XP on disc but it depends of requirements that it may need to work on your XP computer. On 2009 I've ordered Descent 1 and try to see if it works on my XP but it was too fast and difficult for me to control and there is no sound at all which is not very compatible for XP so I tried playing it on my old laptop win 98 and it works great it plays musics but no sound at all just music :( on August 2009 I got a new Vista computer so I tried to install Descent II but had an error saying not compatible with the version of windows that I'm using and I think that game may not like the 64-bit Vista. Thanks to GOG that made Descent 1 & 2 very compatible for new modern computers like mine, I perches that game and it works pretty well not an error that will prevent me from playing Descent 1 & 2. If Descent II would have worked I wouldn't be able to end up looking at GOG and create an account.. Descent 1 & 2 are now stuck in my life lol but I might play my old disc of Descent 2 on my win 98 laptop and it works great on that too.
