I just lazily got the information from wiki.
Some didn't have a page so they have very incomplete information.
I probably shouldn't have included all the assisted titles since most don't have any, but I figured it was easier to have a template that includes it than try adding in for specific ones.
Overall MS is at a pretty decent spot.
Strong points:
Double Fine, Rare, Obsidian, inXile Entertainment, Ninja Theory are pretty big.
Weak points:
Turn 10 and Playground together means that 2 of MS's studios are just dedicated to Forza.
Not bad per se, but Undead Labs and Compulsion games are pretty small.
Expected points:
Coalition, 343 are decent, but they are pretty much dedicated studios to specific games.
Unexpected points:
World's Edge and the Initiative are completely new and it's hard to say how much they'll do.
Some studios are new and don't have a lot of information on them.
