After watching the Daggerfall Random PC Game video, I'm sure a lot of people will want to try out the game for themselves. Bethesda offer the game completely for free at http://www.elderscrolls.com/daggerfall/, but you probably already know that. It's easy enough to start up, but if you're running on a modern OS and your experience was anything like mine, you'll notice that the game is missing sound effects or music, skips cinematics, and generally runs a little sluggish. I'm sure somebody a little more patient and experienced than myself with DosBOX could tweak all the settings to get it running perfectly, but why bother?
Praise Akatosh, this site is amazing! They've packaged Daggerfall along with a few mods and unofficial user-made patches into a nice and tidy, Windows 7 ready setup file. For the purists, all that extra stuff is optional. The key here is just that it works flawlessly on Windows 7. The website's completely in French, but it's fairly easy to get around regardless of your knowledge of the language (and a simple Google translate will definitely get you by).
Here's the direct download if you're sold already and want to skip the page entirely:
Also, note that they did this for Arena as well if you want to check that out too!
