At the time, I bought the DVD version of Skyrim, but didn't pay attention to the fact that it required me to create a Steam account and install it. I still have the computer from then with XP, but now Steam does not support XP for a long time. The same thing happens to me with other games that worked on XP. And the same will happen with Win 7, I have the first Tomb Raider reboot from 2013, I even preordered it, but again It won't work on Win 7 because Steam won't work on Win 7.
In my opinion, Steam/Valve is synonymous with stealing.
The games I bought were stolen from me. To play them, I have to use hacking methods... so why buy games on Steam if they will never be yours, and you have to hack your own games.
Personally, I am very angry and as I say, I feel that Steam stole my money. A couple of days ago I installed the client on Win 7 to remember what games I had, and another frustration, Fallout 3, it also ran on XP
It's been years since I bought anything on Steam.
And, I have computers with Win1 0 capable of running those games, but I want to do with my paid games what I like, and it is playing then on an OS supported by the games when I've bought then.
