I disagree with your position with Steam, but I'll respect your decision.
It is a Steamworks game and will be one until Valve goes under or disbands the Steam department.
As per Steams EULA ( I believe its in there). If Steam or Valve goes bankrupt they are required to release the code that disables Steamworks allows all Steamworks games to be played without Steam (client).
I admit, Steam has some upsides and useful features, but I think security and privacy outweigh ease of use. At least I'd like the choice between using Steam or buying the game in retail.
The EULA part is nice, but sadly in no way legally binding, so it doesn't help even if they go bankrupt.
You need to log in to Steam only once to install activate the game and then use it in offline mode. You don't need to use Steam as a social site.
Steam is used to
1. discourage pirates
2. discourage resellers
3. auto-install patches
4. Allow easy DLC installation for the "casual" user.
5. Advertise the game by means of "Achievements"
When Steam shuts down, gamesas (or someone else) might provide other means to get the game running, means we're not allowed to talk about right now.
1. Obviously doesn't work.
2. This is another way of restricting the consumer's rights. Thank you very much!
3. Can easily be done by the game itself.
4. Same as above and doing it manually is really not that hard.
5. Okay, for this something like Steam might be required. It doesn't have much to do with the gameplay and I don't see the benefit, but that is probably due to my restricted point of view. As it stands these "Achievements" are optional, so the point is moot.
That is all fine but that still requires that you have Steam running and logging your gameplay in the background -- EVEN in Offline mode Steam is running on the system ! Which also means that you have had to create an account with STEAM and give them your personal information including credit card info !! ( and as you know their Forum is currently still down because it was hacked and the hackers compromised their security and got all of the customer info that was on the system including all personal and credit card info (yesparts of it is encrypted and they are not sure if it will ever be used for identity theft but it is a real possibility !)
What the OP is wanting is to play without it running at all or even being installed on his system. (afterall the game is a single player game and there is no reason at all for the internet connection to be needed ( You say it is needed for the DRM but you do realize the game was cracked and the Steam DRM disabled by the pirates 20+ hours before the US official release time was reached so using STEAM for a DRM scheme was an utter failure since the pirates already are enjoying the game with the steam restrictions completely removed ( and even the patch is already available to them as well !) So instead of paying all of that money to use Steam they could have used it to hire more Programmers and BETA testers and get the UI and shadows implemented properly.
Also while Valve may have said they would somehow enable using the games if they ever went Bankrupt there is no way to enforce that and if the company goes broke there is no money to actually implement that so them saying so may make you feel better but there is no way to ensure it will happen and if for some reason Valve decides you have done something even if you have not they can Ban your entire account and you lose access to every game you purchased from them with no recourse.
Exactly my point, plus no one can say what would happen, if Valve gets bought!
And if they go bankrupt, the rights to their products will most probable get sold, so even if Steam gets shut down using other methods to get the now defunctional games running is still illegal! You will be a criminal for playing your bought games.
The longer I think and talk about this, the less I like it.
Thanks for your help guys, but I think, I'll skip this game and play my old, legal ones until the companies understand, that the people buying their games are actually the ones they punish with their restrictions.
