note that 90% of the profit comes from big AAA titles, not from below.

... I get what you're saying, but I think the Unreal Engine is going to continue to be a cash cow for a good while yet.

Digital had bumper profits just before they went under - it's typical, as they go upmarket, to get greater profits. But I'll accept that you get what I'm saying. :)

Another data point: id was killing it (and, to us, Carmack remains undisputed). But they completely lost out the next generation, to Unreal, because of vehicles. I don't think that'll happen here, just disclaimin' past performance is no guarantee of future success.

Though, to be fair, the Quake engine underlied Call of Duty, the most successful franchise (I believe), and it really showed in the framerate. Note: no vehicles. And yes, past tense.

They didn't even open the latest Id tech to public... They didn't even go to the game.

It has nothing to do with vehicles.

It was an example of losing dominance, not to do with open.

Re: vehicles. I'm going by what Carmack said in an interview.

That sounds really weird, do you have a source for that interview?

I agree it sounds weird!

He was talking aboout the time around Unreal Tournament 2004, and at that generation, it was a big thing (kinda like waving grass was at one time).

Sorry, I don't recall which interview (and it would be hard to google unless there's a transcript). It might have been one of his keynotes, perhaps the one with Rage on an iPhone. I'm pretty sure it was a long one (at least 1.5 hours). It was one of the big popular videos on HN/r/programming (not an esoteric one).
