As promised, right on schedule, GameSpot's Prince of Persia 3D Demo is now available for download. The file is available as a big ole installer (described as for "corporate connections"), as well as one of those resumable Gigex stub dealies, for modem users. Word is a DirectX-compatible 3D card with 8MB RAM is required to play, as is QuickTime 4.0. This doesn't seem to be an exclusive, so here's a local copy of the full installer (49.9 MB), along with the customary list of other mirrors.
