I remember seeing this, but I can't remember if I tried it or pegged it for "next time". I also imagine the new engine will have more friendly movement controls. The hardest part of playing good games from the past is when the control scheme hadn't settled in what we now generally consider a superior format, and sometimes the old engines don't take well to those control schemes. IIRC daggerfall was somewhat in this camp (and for some reason I'm remembering it as more painful than arena, possibly because of more vertical space but bad mouse look?)
