Well the reason everyone is against the Always On DRM is because you can only play it when they want you too. There's also the problem if the Origin client or your internet goes out you will lose all game progress after your last save. Another issue is, what happens if EA pulls the servers for SimCity? Guess what, the game you paid for and own will no longer work because EA decided to shut the servers down. Do you really think the servers will be up for SimCity 5 years from now? EA usually pulls servers for games that are more than 3-4 years old. So essentially, you are leasing the game. If that doesn't bother you than I don't know what to tell you!
To play devil's advocate though, The Sims 2 was just recently shut down after 7 years. There is, of course, a newer Sims 3 out that most people are playing. Spore is still up and running as far as I know, and it came out like 5 years ago. This game is likely to be up for several years... and if it is pulled, it will be because a new SimCity has been out for a couple of years most likely. If it lasts 5 years, I will have considered it to be worth my purchase, but that's me. Everyone should know the limitations and make their own judgment about it.
I don't really care about the servers getting pulled, I care more about Origin being down all the time. There's been numerous occasions where I want to play BF3 and I can't because either Origin is down for maintenance or there's so error that prevents me starting Origin at all. I don't like being told when I can play a game that I paid for.
SimCity is a multiplayer game since when? SimCity has never been a multiplayer game till they added some gimmicky features to justify using always on DRM. Always on DRM is not the future and I'm not sure where you get that idea. Explain to me what that type of DRM does to stop piracy? Now explain to me what that type of DRM does to hurt legitimate owners? Do you really think the online features are anything more then something that was added to put the always on DRM in the game?
Either way, SimCity isn't a online game. The online features add nothing to the game, just takes away everything that was fun about the other games. If you like the idea of having tiny maps then you have never played SimCity 4. There's no way you could possibly like having 1/3 of the map size if you played other games in the series.
Yes I played the beta. There was a few things improved on over SC4 but it doesn't feel like a SimCity game. There's nothing about the game that felt like SimCity to me and it just felt like a different game using an established name to sell copies.
