The game could practically run on a smart phone at this point. Actually, I used Team Viewer on my android phone to access my puny laptop, launched the game and could see the graphics halfway decently on the phone, the cursor just couldn't be controlled.
Specifically however:

The installer for the GOG version also works on windows 7, not sure how it will run on Windows 8 yet, would be interested to know, as I've heard Bloodlines may not work on W8:(
