For me, it’s the voice. For a voiced character like V, it requires a very special talent to take you on a journey with them, to listen to their fear, pain, anger and despair. Cherami Leigh just does such a fantastic job of bringing V to life for me, of really bringing that raw emotion out and making it feel real!
Oh, yes, one of my first DOS games, played it lots, but I don’t think I ever cleared the board. Always ended up running into three or four Klingon ships and getting blown up.
