I haven't seen this interview mentioned anywhere on ttlg:
RPGDot: Which of your former games would you like to re-do, if you had enough foundings and time and freedom of choice?
Paul Neurath: Terra Nova. Back around the time Ultima Underworld II was wrapping up, I had the concept for a squad level 3D tactical game loosely based on the fiction of Starship Troopers and The Forever War.
