Big complex game with an engine tweaked and pushed right to the brink of breaking point.
But doing like Valve instead: waiting patiently for next gen and THEN actually organize stuff up for a possible release.
Half-Life 3
will obviously be released, just not for current gen. This should tell something. It's not that Valve are trolls, evil or crap like this, they're just not dumb, and want to achieve perfection like they've always did so far. Valve, and many other
indie companies.
And yes, yes, yes, Bethesda games are complex big, bla, bla, bla. But the dedication should be the same. You know that you have an old, instable engine, you are perfectly aware that next gen is at doors, you perfectly know that if you want to be stubborn and release a HUGE complex game like Skyrim before next gen, when you're engine is what it is (not utter crap, though) then you'll face the consequences of having a game that could have been better (both visually, graphics, eye-candy little nice things and in internally, scripting, A.I. etc). Just saying.
It's not for coincidence that the very first Half-Life game had the BEST A.I. in the known galaxies videogames wise. Why can't Bethesda do that like Valve? Because they're going through the huge corporation thing, which will eventually shape the way the Elder Scrolls games, when in their golden age, used to be (Art. Profit, yep, but mostly art) I loathe companies, especially gaming companies, that do not love their products. That they look at them only as a mean to be famous, get money, massive amount of money.
