I agree, I expected the same and was ready to pre-purchase Civ 6, but then I saw the cartoony screen shot and all the excitement was gone.
I am not paying $60 for a cartoony game.
Actually I was expecting to buy a new computer with Civ6. Now, I see I don't have to. It's not only a matter of "cartoony", it's really a matter of graphical complexity... or over simplicity in this case. I would have prefered Firaxis to find a way to work complex graphics without sacrificing the clarity needed for this type of game. I was pretty confident. This is a huge disappointment.
Worse yet, and from what I read about mechanics, mechanics are cartoony, just like graphics implied. Just like Civ5 and Civ4. They are so arbitrary, rigid and unfun that it's becoming pityful. I definitely won't buying this, and I'm definitely done dreaming about that series.
Not to mention evolutions are shy. They are presented like revolutions, and that is in a way, but just because it didn't existed before is not necessarily what makes it revolutionnary. People are so eager of novelty that they judge innovation within its only character of novelty, not considering any.other.aspect. Ever. "OMG it's new ! Buy buy buy..." This is so impulsive, immature and brainless.
Civ6 is really Civ5.1. I was so disgusted when I saw in the screenshots that rivers was still between tiles, making their navigation impossible. They are still rare and blocky.
Absolutely no effort has been done, this is insulting. And it's what can be seen in most domains, graphics first. Firaxis people are so lazy, untalented, and arrogant.
