Halo: Reach: made $200 million

[superluser]

O, beware, my lord, of jealousy;
It is the green-eyed monster which doth mock
The meat it feeds on; that cuckold lives in bliss
Who, certain of his fate, loves not his wronger;
But, O, what damned minutes tells he o'er
Who dotes, yet doubts, suspects, yet strongly loves!

Unless your primary goal is to do something, there will always be someone else who does it better. If Frictional's primary goal is to make the highest grossing video game, they have failed. If, however, Frictional's goal is to make the best horror video game in a way that sells well enough to provide a stable income for their employees, it sounds like they're close to succeeding.

And as such, let Halo:Reach have its heyday. Its success doesn't diminish Frictional's.
