Vogel's history of aping thoughtlessly whatever is the current AAA wonder continues. You know, thinking about it, maybe the reason Exile 1-3 were good was at the time he was just copying the then relevant Ultima. I guess maybe he was always this way, it's just that what he's shamelessly copying is now so much more degenerated.
I agree that Vogel takes liberally from good ideas in other games, and that the difference in his more recent games have been a reflection of that. Taking good ideas from other games is what developers should be doing, though, and I disagree that he did so "thoughtlessly" or that he was "just copying." The combat in Exile is much better, the exploration is much better, the world is more packed and makes more sense (you don't tend to just have cities in the middle of the wilderness), the setting is actually interesting and not just a Garriott powerlarp (and no "Ye olde English" garbage), and there's thankfully no first person dungeon exploration. Though it was clearly inspired by Ultima, the Exile series is quite different and I'd argue better than the Ultima's (at least the Ultimas I've played).
