It's one of those typical cases of "Let's forget the fanbase we built up over the years and move to a completely filled up niche for some strange reason."
Settlers was renowned, original and legendary in its approach. The slow pace, the satisfaction you felt when you produce your first gold soldier - knowing you've set up everything right, and that you're ready to invade. Building up your economic chain to squirt out that last gold coin you need to buff up your soldier so you can take that last castle... There was nothing like it. It's what made 'Settlers': it didn't make it a hit, but it did make it a damn good game. It had its fans, and its fans were loyal.
So, now they apparently decided to make it an oldschool Age Of Empires clone. Another one. And a very bad one at that too, apparently.
I don't get why game publishers do that, really. Allright, the Volkswagen Beetle sold well - did that mean that Mercedes or BMW suddenly turned their production around and only produced Beetles? No. They continued building their cars, because they were smart enough to know that Volkswagen and Mercedes catered a differend audience, and the Beetle-market was almost completely filled up with Volkswagen's cars anyway. They may not sold as much cars in numbers, but by God - their cars are legendary too. And they're still around, and they're still making money.
The stupidity of game publishers continues to amaze me.
