1. I'm not going to buy it.
2. Destiny 2 has too many of its own issues. If you fix all of them, you've just made Destiny 3
3. If Destiny 2 is supposed to lead into Destiny 3, then just make it lead into Destiny 3 by itself. The same way Destiny 2 is now just called Destiny 2 Forsaken. Destiny 3 can just be the final era of Destiny in Destiny 2.
4. Again I'm not going to buy Destiny 3. I've spent too much time with this game as is and most of it Jas been in a love/hate/frustration. There is always something wrong with this game. No game is perfect, sure but at this point there really shouldn't be this many issues in this game. I heard about D1's troubles and about how it turned around and became a better game, and thought D2 was a good entry point into the series. I was horribly wrong. I'm not making that mistake or taking that risk again. But while I am here, playing D2, I want D2 to be the best it can possibly be, and I think the only way it's going to do that is if you just drop 3. Period.
But that's just my opinion. Don't get me wrong I've enjoyed D2 but it can be so much more. Destiny as a franchise can be so much more. And more profitable than it has been. But you have to make a good game first. Good games make money. Period
