Come on guys. It's just impractical to set up x100 bandwidth and hardware, if it's only required for 1-2 first weeks. What's the big deal? The rush will subside and the game becomes playable again. Don't want to buy and be not able to play? Well you are not in kindergarten, you know what happened with Diablo 3. Just wait a couple of weeks and you'll be good. And the always-on thing? Annoying as hell, yes, but I don't think you can't say that "no one proved that it's effective". It IS bloody effective no one was able to play Diablo without paying for it, and if Simcity is engineered right it will be the case too. And this is where money is. Grumps of minority are really immaterial. The game WILL sell and it will sell well. There is simply no logical reason to NOT have always-on DRM.
Now the Ubisoft argument. Well, their always-on DRM was cracked. This is I think why they tool a step back. But it was cracked only because the implementation was clumsy - it was a patch-on. The games still were happening on the client and server was only used artificially to check some kind of sequence codes. If the games were happening on the server, like Diablo 3, there would be no way in hell it could be cracked. So I'd consider Ubisoft retreat as just a regroup.
The future of AAA game is in always on, that's just economics, so it's better to get used to it. Indie is very strong now, so it's not like we are going to end up without games at all if we choose not support AAA. But this kind of resistance is really futile, the only people harmed by it are ourselves.
