I considered the expansion, but I wasn’t interested enough in D3 to even finish it, the always online still bugs me especially because they removed it for consoles, and the new stuff just earned a big “meh” from me.
As strange as it may seem to say, the writing in D1 & D2 as simple, but very good. It got the point across, set the mood, and was done. The writing in D3 started bad and went to worse, until by Act 3 I simply couldn’t take it seriously anymore. Their attempts to revive the tension and psychological heft induced snarky comments and grins. Their attempts to go M0AR! EPIK just made me roll my eyes. Sure, Diablo was never about the story. But it was heavily about atmosphere and that was completely missing.
And then, on top of that, the game was just, “OK”. Not great, not bad. I could play it for quite a while if the flow was good, but the odd bit of lag would irritate me, the lack of interesting strategic choices made it boring, and the overall repetitive grind made it dull. I quit because there were simply far better options to spend my time on, and even if D3 was free, it just wouldn’t be worth my hours.
