I like all Blizzard games that came out before Diablo 3, it’s hard to pick a winner. Probably Starcraft 1 if I need to pick one, I’m horrible at it but this game was pretty damn close to perfection in its genre.
I also really liked Hearthstone at launch, but I haven’t turned it on after it began deprecating old cards and has devolved into a monetization trap. Screw that, I’m out.
Absolutely hate Overwatch, Heroes of the Storm and 2018’s Hearthstone. If those are what Blizzard’s future is like, there is no qualitative that can describe how little I’m going to care about Blizzard’s games in the future.
