EPTa lot of people have been asking over the years if we could figure out a way to get Spending Quotient and other interesting stats about our matches. there is an interesting file that i believe contains all the stats that are shown in the Summary Screen after a game completes.
it's the s2gs file. You can trigger arbitrary *.s2gs files to be downloaded to your machine by viewing game summaries in the SC2 client. In SC2, go to your Match History, then click on one of the magnifying glasses. That will trigger a new s2gs file to be downloaded to your machine.
On my Mac, they're in paths like this:
/Users/Shared/Blizzard/Battle.net/Cache/69/61/6961b3a6c6c294dbff91a786d60fddea962e70b01a040a5c7a096987896a2e0e.s2gs
On PCs I'm told they are here:
C:\ProgramData\Blizzard Entertainment\Battle.net\Cache
The easiest way to find a s2gs file is to look at some match summary screen in the game client, then go to the directory and sort by date modified.
If we all put our heads together, I bet we can figure out the format.
A fellow SC2 nerd, Nick, was able to get this far:
#!/usr/bin/env python
import zlib
data = open("test.s2gs","rb").read()
print zlib.decompress(data[16:])
Some of you may wonder about what Blizzard's reaction to this project will be. I hope that Blizzard will have the same reaction that they've had to the community's study of the structure of the MPQ and the replay format -- essentially none. Of course, if Blizzard prefers that this project not move forward, I for one will cease immediately.
I'm not sure what's the best way to structure our findings -- I guess people can post what they discover in this thread, and once that becomes unwieldy, someone can set up a wiki or public Google docs page to hold the findings. Or a github project.
You might be asking, what's the point of being able to parse s2gs files? Basically every tool that does anything useful with replays could parse s2gs as well, and all the info that is visible in the end-of-game summary screen could be merged with the replay info. For example, computing Spending Quotient would be trivial. There are about 30 other cool things would be immediately quite doable.
