I foudn them. Are they worth getting? How fun are they and are they really glitchy?

also do i need DOSbox to run them?

Yes get them, neither are very glitchy, yes you need DosBox.

How the hell did you find them? Do they come with the boxes and manuals?

does Dosbox harm your comp, cause i dotn want to screw it up.

Arena is http://www.elderscrolls.com/downloads/downloads_games.htm, but if you want the box & manual and stuff, go for it.

Redguard is a decent fun game, but also fairly hard to get to run properly on a modern computer.

No, it doesn't.

For Redguard I recommend using Glidos and VDos32. However Glidos costs $10. There is a free version of it, but you then get a huge 3D logo spinning ingame. Though you could try the tutorial in the sticky here, but I couldn't get that to work at all, however the Dosbox CVS version that's recommended for it was the only one I could use to get Battlespire working properly for some reason.

I enjoyed both of them, though they are quite different to Morrowind and Oblivion, if those are the ES games you started with. I would recommend at least giving them a try.

You don't need Glidos. I got the game to run using the dgvoodoo method on the http://www.uesp.net/wiki/Redguard:Installation_guide. It takes time, but it works. You need a mounted image of the CD for the cutscenes to be smoother.

That same site has a method to get it to work on DOSBox, but I did not try it.

I've tried that one several times, but I just couldn't get it working for some reason. :shrug:
In the end I go tired of the headaches, and decided that $10 isn't really that much. Especially since I got Redguard as a gift from someone, so I hadn't spent any money on it myself.

I only wish that they'd fix the music, it's still good without it but it would sure be better with it.
