Now, they are completely changing the way they do business. Who wouldn't be concerned?
That announcement by itself isn't enough to make me concerned. But I am concerned by the other announcements that seem along the same line. Charging for character customization in WoW (not that I play it, but it's a step in the "wrong" direction, imo). Claiming that they'll have some sort of "pay" option in Diablo 3 for... well, no idea yet, but I can't think of anything that'd be good. Adding console-style "health/mana bubbles" to Diablo 3. Removing standard units from Starcraft 2 multiplayer.
Taken individually, again, each one of those is questionable. But taken as a whole, it has me greatly concerned. I've played all the single-player Blizzard stuff in the past (ie, everything but WoW), and enjoyed them. I was excited for Starcraft II and Diablo III. But the more I hear about them, the more I start to wonder if they are going to end up shooting themselves in the foot.
I suppose that's the wrong term to use - I expect that they'll do tremendous business, because, hey, they're Blizzard, and everyone and their dog will be getting the games. I'm more worried about what it'll do to their reputation if it turns out that they
are going to start nickle-and-diming people. Blizzard got their reputation by putting out top quality products, and going the extra mile long after other companies have moved on (check the last patch dates for Starcraft and Diablo II). But it's one thing to earn a reputation, another to keep it. And, frankly, their reputation hasn't been tested in a long time now (Warcraft III expansion would be the last game I can recall - I don't count WoW in the same vein). I really hope that it's not overrated.
