First off, these fears are based off the fact that NV required Steam and it is therefore a sign that Skyrim will too. That is a wrong assumption to make, or at least it is an over reaction. Why because NV was made by Obsidian, not Bethesda. Putting NV solely on Steam was, I believe, THEIR move to make, not Bethesda's. The reason I think this is due to the fact that Bethesda said that they had as little involvement in NV as they possibly could, because it was interfering with the development of Skyrim. There is no official evidence to support this claim, but if you look at the behavior of both Obsidian and Bethesda, you'll see that putting NV on Steam was much more likely originally thought of by someone on Obsidian. Although Bethesda most certainly had to approve of the idea because they where producing the game, and putting the game just on Steam would influence sales in some way, for better or for worse. So this means that Bethesda thinks that Steam is a good and trustworthy company, but that doesn't mean in the slightest that Bethesda themselves are considering using Steam for their own games. Bethesda is a very independent company, they do just about everything themselves, and if they aren't doing it themselves there watching over it like a hawk. I think Obsidian used Steam because they are a relatively weak gaming company, and they couldn't have handled the job themselves so they got Steam. Bethesda doesn't need help like that, besides TES are their child, and I don't think they would entrust their child to another company, even if they think it's a good company that can get the job done.
All that being said I'm going to start going through the misconceptions I've seen on these forums.
Misconception #1: Skyrim WILL come out as a Steam only game. That is most likely not true, in fact I'd say the odds are quite slim. (see above for reasons.) That being said there is a chance, all be it a small one.
#2: You have to have an internet connection to play Steam games. Wrong. You only need an internet connection when using Steam to download Steam form www.steampowered.com. (A process that takes less then five minutes), download direct to drive games, active CD keys, update games, and play multilayer. Otherwise you can put it on offline mode and play just fine.
#3: It's impossible to put Steam into Offline mode, and if you do succeed eventually it will switch back to online mode while your playing. Wrong. Switching to Offline mode is very easy. If your already in online mode you simply click the button in the upper left hand conner that says Steam, and you then scroll down and click Offline mode. A common problem with Steam before was that if you started the computer without an internet connection it was very hard to get it to go into offline mode. That has been fixed, now whenever it can't connect to the internet it will ask you if you want to try again or go in offline mode. Once you are in offline mode it will not switch to online mode until you tell it too. That's a fact.
#4: Steam automatically updates your games, whether you like it or not, and theres nothing you can do about it. Wrong. Games start at the default "Always keep this game up to date." option, but you can change this at any time by right-clicking on the game in the library then clicking properties. A tab that says Updates should be visible. You click that to change the update stats. Once you tell a game to not update it will stay in that mode forever, unless you reinstall it or change it.
#5: You can't use mods with Steam. Wrong. Mods work perfectly with Steam. You just have to keep in mind that Steam saves it's game differently then normal. You just have to follow the path C:/programfiles/steam/steammaps/common/skyrim/data/. If you follow that you'll find the right spot to put your mods.
That's it for now. I may add more misconceptions later.
This topic is less about whether or not Skyrim will require Steam, and more about how Steam works, so you guys know what to expect if it does.
