Not much controversy, at least not when I read the comments.
So, perhaps here's for some controversy:
First, I am like Drew: I have played and loved Oolite, but I never played any of the "sequels". All my knowledge about them is from third parties, and most of it stems from—surprise, surprise—these very boards and the Wiki (and Selezen's site). If I understand and interpret everything I know correctly, I come to the assessment: Frontier is probably a good and captivating game in its own right, but it's
not a sequel to Elite, and never was. It doesn't share the same premise (in which GalCop and Thargoids play a big part), and it doesn't share the same universe (apart from some alibi systems). I think that I once read either here on the boards or in some other place that in fact it was developed as a distinct space game and simulation, with no connection to Elite at all. Then David Braben got into it and slapped some superficial Elite material into it (a couple of planet names, a couple of ships), in order to be able to market it as a sequel. So, the name "Frontier 'Elite 2'" is basically a marketing gimmick, in order to appeal to those people who played Elite before.
"Frontier First Encounters" then applied some more of the Elite material (Thargoids) to the Frontier verse. But it's very clearly a sequel to Frontier, not to Elite.
When "Elite:Dangerous" was announced under this name (not under the name "Frontier:Dangerous"!), I briefly had the hope that it would be a sequel to Elite, but the more information was revealed, the clearer it became that this would not be the case. In contrast to what its name suggests it's actually another sequel to Frontier, not to Elite. (Still, I threw a lot more money at it than I should have (but I don't regret supporting you guys, only pledging for the game itself).)
So, that's the situation as I see it. As far as Elite sequels go, Frontier has been sailing under a false flag right from the beginning. Marketing-wise this was probably a smart move. But in my opinion it doesn't really do Elite justice.
However, the story doesn't end here. Actually, there
is a true sequel to Elite, and we all know it: it's Oolite. Staying with the premise of the original, and then innovating and expanding it, that's exactly what a good sequel does.
Thus, for me Oolite is the only "Elite 2" that ever existed. In a parallel-but-strangely-connected-(leading-to-much-ugliness-and-confusion)-universe there is also "Frontier" and "Frontier 2", and in a couple of months we'll have "Frontier 3". I would be happier if the distinction was a little clearer.
