This is really nice of Blizzard, but I have a friend who got a virtual ticket to Blizzcon this year, and he tells me Diablo 3, on the other hand, is basically being tapered off.
I think Diablo III was a bit of a lost cause from the start, Real money auction house killed off much of the player base at launch (loot drops balanced around buying/selling rather than personal acquisition) and the game changed drastically over time as well. Not to mention you were forced to go through the difficulties from normal to inferno on each character (so you had to go through the same story constantly). It quickly became repetitive, nowadays it's a pretty decent game but I'm no fan of the focus on seasons and rifts. This is one thing I've come to dislike about Blizzard, if you buy a game and enjoy the product, after a few years (or sometimes months) it just won't be the same game anymore. Some might say that's nice but if you look at Overwatch for example your favourite character risks becoming boring to play with all the drastic changes to characters such as Soldier76, McCree, Roadhog, Genji, Mercy etc. Obviously balance is important but I think it can work both ways for a game.
Good points that I can't argue with. I put Diablo 3 down from late 2012 until basically 2016, because it originally sucked so badly. I put it down again this year, because now the game revolves around, as you said, seasons and rifts. It's like Blizzard isn't even trying with D3 anymore.
As far as balance, that's been a thing with Blizz since WoW became popular. I think it's a way for them to keep the meta fresh, tbh, though it can be frustrating.
Let me guess.. Always online & DRM
There's a reason I avoid Blizzard products since 2003, because they have to make EVERYTHING
There's no DRM to speak of, other than having to be online for achievements. iirc there's a way to play the game legally without battle.net, but I'm unsure how, because I barely play it (not much of an RTS fan, though I admit to owning this series)
