Well I'm not. The time you have mentioned I probably wouldn't be involved in independent game development as I don't have much money. I understand things were definately worse in the past, in most cases they are. However in this market independent game engines are competitively priced now, which is great because I have so much more options for my money. If I'm not completely satisfied, it should be only natural that I at least consider other engines.

I agree there should be both free updates and ones you have to pay for to keep development going. However when I finally pay the previous version better be done and perfected and the next version should be moving along and relatively bug free or it should stay in its beta stage. That's just my opinion.

I like the concept behind A7, but I don't feel as though it has really evolved enough from A6 that I want to buy it again. And I personally fear that the next version will be released before A7 is what it truly should.
That's just how I feel. I'm not trying to convince anybody of anything.
