I seriously doubt a game designer would accept much criticism on game design issues from beta testers. After all, he's the lead game designer for the most successful strategy game ever and they are just beta testers, why should he think they are right and he is wrong ?
Sorry, but what would be the point to have beta testers, then?
"Don't tell me where the game doesn't work, after all *I* by the Lord's Grace am the lead designer?"
Of course after reading Sulla and Dale posts you would think they are way better than Shafer at game design, because they are very good at pointing out his mistakes and really it's difficult not to agree with their points. But that doesn't mean that they would be able to do better then him. Finding someone else's mistakes is easier then making your own design.
Of course it is much easier to pick out the flaws. No doubt about this.
And I am far away from claiming that either of the two you mentioned would be a better designer.
Well, maybe they would be slightly better, since I regard Civ5 as a complete desaster.
The UI is a slap into the player's face, but was heavily advertised for "accessibility".
The combat is so poor that it is hard to put in words. Three months after release. But it was heavily advertised. Actually, it was the *one* thing about which they talked all the time.
Diplomacy is completely erratic. You could as well roll dice. And it has already been significantly changed.
The engine is hardware demandin like no good. The relative output compared to the demand is poor. Yet, it was advertised as "scaling and even been developed with the help of Microsoft"
The whole game feels like everybody in the development team was allowed to create his own "baby" and then they tried to combine it all. And they failed.
So, yes, even Dale and Sullla might have been better leads, as it is hard to imagine it getting even worse.
After all, we are not talking about the first garage-made game from an indy developer, but about the last iteration of an almost 20 years old franchise. There should have been some lessons learned from the past.
