I would not count Rare as a good acquisition: Microsoft bought them for $375M, and they haven't produced a single hit since. To put that in perspective, Bungie (a much smaller studio than Rare at the time) was acquired for less than $40M, and their games and IP generated over $1B (and counting) in revenue for Microsoft.

I could be wrong but I remember reading that the second MS bought them, all of Rare's talent left.
