I beg to differ - Dragonflight is fucking incredible and Diablo 4 is looking like it will be absolutely Stellar. Original OW was good, but sequel is doo doo. Starcraft 2 and all of its expansions were amazing.
Hearthstone spiced up the card genre. Diablo 4 will reignite ARPGs.
D2 Remake is phenomenal as well.
Can't wait for them to set the standard for the Survival Game they're making.
Lets see what you have here:
Dragonflight: Probably fine, doesn't look great though. At this point I'm not going to touch WoW, too much new stuff to play but am glad that they managed to get it back to "okay" after the last few expansions.
Overwatch: Totally over-rated. A fine game, but not great or even innovative, except in its marketing.
Starcraft 2: Dog shit. Ugly bullshit, worse than the original, which most people then went back to.
Hearthstone: Card game, don't care and never played.
Diablo 2 remake: A remake, impossible to fuck up (except they totally did with Warcraft, which I see you neglected to mention.)
I can't help but notice you neglecting to mention the most relevant comparisons to D4 though, Diablo 3 which launched awful with the auction house fundamentally breaking the game and an art style I didn't approve of to boot and the recent mobile Diablo which is apparently a money vacuum.
