Back in the day sure, but the blizzard of 20 years ago is long gone. Diablo 3 is an abysmal followup to D2, every CoD is just an annual rehash, hearthstone is an absolute moneygrab, and HotS is the most watered down moba I've ever played.
Overwatch is cool though.
edit: and oh my god, let's not forget the absolute dumpster fire of warcraft 3 reforged.
D2:R was mostly Vicarious Visions (but it absolutely did turn out awesome).
WoW (retail) has had 3 of its last 4 expansions ultimately perceived as failures and is (justifiably, belatedly, finally) having its lunch eaten by the vastly superior Final Fantasy XIV.
Immensely is probably overstating Starcraft 2's popularity, but what popularity it still has is in spite of anything Blizzard has done for it recently rather than because of it. They've essentially abandoned the franchise to wither on the vine at this point.
This is the first acquisition, possibly ever, that I view as potentially a positive for the customers of the company being acquired, if only because Microsoft can't possibly mishandle Blizzard's IP and staff any worse than Activision and Blizzard already have.
Overwatch is cool though.
