*shrug* We disagree.
We'd rather make a campaign that gets a hundred overjoyed, amazed reviews and a few mediocre ones than a campaign that gets a hundred 'okay, that was pretty good' reviews.
That reviewer liked Blue Planet. The community like Blue Planet; it's the most popular campaign out there right now.
Most people love Blue Planet. We're not going to stop having characters. We're not going to abandon the mytharc and mysteries set up in AoA, even if we step away from them for WiH.
See, if you let mixed reviews stop you, you're ignoring the fact that
everyone loved Blue Planet.
If you tell a strong story inevitably some people are going to disagree with the decisions you made. The answer to that is not to make a tepid story that everybody finds inoffensive. A good story takes risks, it bites.
What we did in War in Heaven is very different from Age of Aquarius. It's definitely more gritty and grounded then AoA; there are no parallel dimensions. It's a story about a group of soldiers and the psychology of war. You can decide for yourself whether you like it or not.
