I think that the no espionage version of the game should resemble the pre-BTS situation. That was a balanced situation. You can't say that Warlords was balanced because it was made by Firaxis and that BTS with the no espionage option (with espionage points replaced with culture points) is equally balanced because it was made by Firaxis. Both models of the game have a radically different balance, they can't be equally well balanced. Not everything touched by Firaxis is golden and everything else rotten.
I'm certainly not arguing Firaxis is perfect and always makes great decisions. But removing espionage (without replacing it with anything) does not make it equal to Warlords. Firaxis added wonders, techs, buildings, and other things between Warlords and BTS. Some of these involved espionage, and some didn't. I'd be foolish to argue its perfectly balanced, but it attempts to be. Removing
only the espionage aspect of the game leaves the game less balanced. Their design choice in the 'no espionage' version seems to attempt to address this by giving some benefit to the parts of the game that otherwise would have less value.
Again, I'm certainly not saying they implemented this choice well; it was probably dictated above all by a lack of time to do it better. I do think they thought it was better than replacing espionage with nothing.
Sometimes Firaxis doesn't go for the best option just because it is financially non-attractive. Creating massive patches for an option that few people use for an expansion pack which was created for the fans and not the big public is one of those financially non-attractive actions. That doesn't mean that we, the fans shouldnt' go for the option that we as fans think would be the optimally patched situation. And we, the fans decide what the optimally patched situation is, not Firaxis.
I think the fans should play whatever version they most enjoy. If that means every fan has a different version of the game, that's wonderful. That's the power of firaxis' decision to make a heavily modable game.
What I am arguing is that this isn't a 'patch' you're proposing, it's a mod. Their design choices for the 'no espionage' appears to be 1)
remove all espionage elements from the game and 2)
replace those elements with other elements of value, chiefly culture. When you toss out 2), which is one of their main design points, you're not 'patching'.
Again, I say people should play it however they want, but if it's offered as part of an unofficial
patch, I think it should be labeled as another option (
Solver's no-espionage version). It should be offered alongside Firaxis' version, rather than replacing it. I wouldn't be surprised if it was more popular than the Firaxis version. I'm not arguing about popularity, only about what should be labeled a patch.
