Being an "old guy" I have some pretty strong feelings about what are my "consumer rights" - as strong as they are old. It's not about not following tech, it's about not wanting to weave (?) all my rights as a consumer. DMCA and similar acts (I'd even say most copyright related acts and slip in bills) is a disaster (imo) - but few seems to care - most even endorse it
Will I buy? Time will show. Maybe it's time to call it a day and toss in the towel, wrt gaming - which used to be fun.
You don't have to worry about consumer rights.
You buy the game retail, install it, log on ONCE with steam and activate it, go to offline mode (works perfectly fine since 3 to 4 years) and play the game offline as long as you wish.
See it as copy protection methode where you have to go online once.
If one day Steam doesn't exist anymore they said they will release a Steam emulator patch so all games are still playable.
You own all the games and have the retail versions sitting in your shelf smiling at you.
What Steam gives you additionally is, that it updates your games if you're online, they built in an screenshot manager a short time ago and, very useful IMO: You can access the internet browser (e.g. for the elderscrolls forums) ingame!
Of course there is also a clock that tells you how late it is. Just press two buttons and you can access all those features.
The big disadvantage is IMO, that if you alter game files like the skyrim.exe, Steam will repair it because it thinks something happens and your game is broken. (Of course mods do work without a problem).
Try it and see if you like it. Don't judge about Steam because of the people writing here or elsewhere.
Steam was difficult at the beginning. It really was. The offline mode was buggy, as well as many features. But now, after 8 years, it works perfectly fine!
