When someone beats me, I like to go back and watch their game in the review game thing. I think it would be extremely useful if you could select who's economy you want to view in the replay (probably a check box like the one you use to select which players you can see). This would be a lot more useful for players who are learning because they can see things like how often the other player exhausts their resources etc.
Spectator features are already in the words and will have features like this (and more). I can't wait.
This doesn't work for me. I did a test where I gave the ai 100 economy rate and then I just built tonnes of stuff so mine was negative the whole time then watched it back and it only showed my economy That's cool, thanks!
