As far as TES are concerned, yes they are great. TES Arena was my first RPG and it caused my addiction to good RPGs. In some sense, TES Arena is worse than heroine. TES Daggerfall was, IMHO, not so good: super huge dungeons (so that you were unable to exploit them completely) but all of them awfuly super the same. TES Morrowind: the same story as with MM9. Our game market is monopolized to large extent so that if they decide to translate the manual then we have to wait until they release the "localized" version. I am left with running arround the shops with enough money in my hand and waiting for the Day 'D'. But this is not what I wanted to write about. You might experience considerable problems when you run Arena and Daggerfall on contemporary computers.
1. TES Arena: if you have a PS/2 mouse (and who does not have a PS/2 mouse nowadays?) then the game might tell you that you haven't enough memory (even if you have enough memory - Arena wants 603 KB of conventional memory) and quit. I suspect the EBIOS area stored at the end of the conventional memory. Perhaps, Arena makes a mistake when it evaluates the amount of available memory. Arena runs without problems with a COM mouse.
2. TES Daggerfall: too jerky in the DOS session under OS/2. I haven't tried Daggerfall under Windows. Worse, if you have a faster processor (I have PIII 550) then the game locks frequently when you attempt to backtrack: you command "Back! Now!" and - nothing happens. This is not the problem of the mouse. I tried both PS/2 and COM mouses. Also, it is not a problem of an emulated session. I tried pure DOS as well. I've never seen the problem when I run with P233 MMX.
Moreover, because both Arena and Daggerfall are DOS games, you can experience problems with the sound card. If your sound card emulates SB16 then all is fine but if it does not...
