I get what you are saying and it doesn't affect me because I work during days on Tuesdays, but maybe I wasn't making my point clear enough. I'm pretty sure every other game that has remote servers require maintenance but I don't recall a single one that takes their systems down, even the solo play games, for 12 hours every single Tuesday for maintenance. Like you said, they all need maintenance, but I find it hard to believe that the Diablo game servers require that much maintenance that often when no other game companies out there do it like that, but Bliz somehow gets a pass because that is just how they do it? I could see them doing it during a launch week or for an older game like WoW with that amount of players and content but Diablo? I'm not arguing that servers don't need maintenance and I'm not saying the cost would be within reason, all I'm saying is that it amazes me that we have that much apathy to let them continue doing this to a solo-centric game for years without anyone questioning it. You would think that if it was that much of an issue, more companies would do it that way for that length of time.
You keep calling diablo 3 a "solo play" game, that has nothing to do with it. Calling an obviously online multiplayer game "solo-centric" is silly. If they were going to make an offline SP only game, they'd have done it 2 years ago. The fact that people are still harping on about this 2 years later is mindnumbing. Blizzard isn't going to change that. Even still, it's an online game, and whether you're playing solo or with other players is irrelevant. Blizzard doing scheduled maintenance(required or not) on Tuesday morning has been the case for a decade now, and likely isn't going to ever go away. As I said, simply having a regularly scheduled maintenance period on a Tuesday morning(likely chosen based off of looking at statistics about play times) isn't a big deal, and you don't get surprised by it.
Or do you think that blizzard should abandon the regularly scheduled maintenance model and go to a random maintenance model that happens less often but surprises people who might have been expecting to play? Frankly, I do wish more companies would introduce a regular maintenance schedule for their games and sticking to it, doing maintenance as necessary.
You made some other silly statement about maintenance being 12 hours every Tuesday, that's just a flatout lie. If you're going to complain about something, at least use facts. Blizzard's Tuesday maintenance is not 12 hours, and even taking 9 hours is a rarity. Between that and your insistance that this is a "solo play" game(Blizzard doesn't even have any current singleplayer games other than RTS campaigns). Calling it a "solo play" game just because you choose not to play the game with other people is being dishonest. Whether you're lying to yourself or trying to spread some sort of misinformation is irrelevant(the Diablo franchise has always been a multiplayer game series anyway). This isn't the same as Sim City from EA "maxis" that was a single player game that EA decided to tack some bs multiplayer features onto that hardly anyone cared about.
