My Take on Hoi3 & 1.3
To start off with, I really liked HOI and HOI2. But I think some people are remembering the enjoyment, and not the pain. That is a testament to how good the good parts of these games are.
As for criticisms of the interface, my view has always been that most players cannot fix mechanics, but they can learn to work with the interface with a sufficient investment. I don't think there are many casual players here.
I have struggled with, and will continue to struggle with the new model of unit control. I don't blame the developers for that. I know that if I had a vote, I would have voted to make the HQ approach optional. But I know I do not have a vote, and should not. I am happy (sort of) with that particular struggle.
CTD I will not put up with. In my view, all must be fixed.
AI spam behaviors, map errors, and game-mechanics failures I am not "ok" with, but I know I have to tolerate a certain level of them. And I will. Those are what I want fixed but on a weekly or even monthly basis is not reasonable. I am perfectly capable of putting the game away for a month or two while waiting for a particular fix in that arena if I cannot tolerate it. It is not like a new game comes out that often. And I am fresh for the game after a substantial rest.
So my view is: If you enjoy it now, play it now. If you don't enjoy it now, play it later. If we are not totally perfectionist, it will eventually get to where we need it. If we are reasonable.
