Ex-Sega guy here. I'm thinking that everybody who thinks a third installment is a good idea never played the first two. They were early stabs at sandbox games where you could go everywhere and do anything. They also were not that good, with monotonous tasks, cumbersome fighting, and comically off dialog. What sounded so amazing in 1999 has now been done a ton of times.
