This link go to full versions of both games as well as the DOSBox needed to play on modern machines. I haven't used these specific downloads myself so let me know if there are issues with them.
ArenaDaggerfallADDENDUM: If you think the game runs remarkably slow, there is a fix. Hold down CTRL and then press F12 to a point where you think it performs well, three or four times should be enough. If you think it suddenly goes too fast then hold down CTRL and press F11 to slow it down again.
