Windows "Windows XP was the last client version of Windows to include the Pinball game that had been part of Windows since Windows 95. There is apparently speculation that this was done for legal reasons. No, that's not why." I love these stories.

Very insightful. Beyond rounding issues, it's always bugged me a bit too that the resolution of game coordinates become worse and worse the further a player gets away from the origin. Therefor if your running precise mathematical computations in a game (ie object projections), the results inherently depend on which arbitrary digits the mantissa is representing. Using integral/fixed point arithmetic would offer equal precision at all coordinates.
