As the Diablo 4 beta approaches, we can't help but dread a demon from our past: Error 37

Remember Error 37? We first encountered it on May 8, 2012, one week before the launch of Diablo 3, when Blizzard gave us a heads-up that the error might pop when we tried to get into the game on launch day—but it was "no cause for concern," they told us. Just, you know, give it a minute and try again.

Of course, it very much was a cause for concern. The Diablo 3 launch was "shaky," as we put it (very gently) in our summary of the release day situation. Servers were crushed as people struggled for hours to get in: Our "review as it happens" reflected the mood of the moment, calling the rash of errors, disconnects, and progress resets "utter bullshit." 

Blizzard was able to get things stabilized for most players within a day or two, and we ultimately gave the game an outstanding 90% in our full review. But the scars remain on Metacritic, where Diablo 3 to this day holds a lowly 4.2 rating across more than 10,000 user reviews. 

And the mess reverberated beyond just review scores and angry comments: Blizzard refused to issue refunds to frustrated players in South Korea, which led to formal complaints and a stern talking-to from that country's Fair Trade Commission. Attitudes were quickly adjusted, and a few weeks later Blizzard's "no refunds" policy fell by the wayside. (In South Korea, at least.)

And despite all the years past, fans haven't forgotten:

What was particularly infuriating about the whole Error 37 debacle is that it prevented players from accessing Diablo 3 at all, even if they wanted to play the singleplayer campaign. Diablo 3 is always online, even if you're playing by yourself: Blizzard co-founder Mike Morhaime explained after it launched (and while players were still dicking around with its various issues) that being connected to the internet full-time was "critical" to Diablo 3's "long-term integrity," apparently even if it meant people couldn't actually get into the damn thing.

(Morhaime also defended the infamous Diablo 3 Auction House, saying Blizzard aimed to "provide convenience and peace of mind" for players who might otherwise be tempted to use third-party marketplaces to buy and sell items. The Auction House ultimately went away, more than a year after Diablo 3 came out, but the always-online requirement remained.)

The whole thing was such a mess that, you guessed it, there were memes:

I remind you of all this because, after long years of waiting, Diablo 4 is finally on the way, and public beta testing is almost upon us. First up is a closed beta test for everyone who's preordered the game, which kicks off at 9 am PDT on March 17 and runs 12 pm PDT on March 20. An open beta will follow a week later, from 9 am PDT on March 24 until 12 pm PDT on March 27. Don't forget that North America is currently in Daylight Saving Time while Europe is not, so you may need to adjust your timing accordingly, depending on where you live.

Preloads for both beta sessions will begin at 9 am PDT/12 pm EDT on the Wednesday before—so, March 15 and 22. The closed beta test will include three character classes—Barbarian, Rogue, and Sorcerer—while the open beta will add the Necromancer and Druid to the mix.

And in case you'd forgotten (it's been a long time, after all), Diablo 4, like its predecessor, will not have an offline mode. Which takes us back to the beginning: We've come a long way since 2012, and mandatory internet connections are almost the norm at this point. Yet online games always seem to faceplant to some extent when the doors first open. The Diablo 4 beta may follow in that tradition (frankly, I'll be surprised if it doesn't) but let's all cross our fingers that we don't have to endure another error code that's so common it becomes a meme.
