This thread ends up feeling like OP followed me into Costco today and started telling me how great Walmart is.
AS882010M0: Besides, with steam games, those 2 pieces of software cannot be used to crack games you do NOT own, impossible. You have to buy the game to download it & updates or verify files delete or replace the "cracks". I am detaching from Steam by freeing my games.
It doesn't matter. If you actually read things like the Steam's subscriber agreement and any end-user licensing agreements, you would know that everything that you buy through Steam is only a subscription, not a purchase of a game. You understand that you're not promised or guaranteed to always have access to what you purchase.
The exact wording is:
C. NO GUARANTEES
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, NEITHER VALVE NOR ITS AFFILIATES GUARANTEE CONTINUOUS, ERROR-FREE, VIRUS-FREE OR SECURE OPERATION AND ACCESS TO STEAM, THE CONTENT AND SERVICES, YOUR ACCOUNT AND/OR YOUR SUBSCRIPTION(S) OR ANY INFORMATION AVAILABLE IN CONNECTION THEREWITH.
Case in point - There was that time when Ubisoft shut down the DRM servers for Might and Magic X and kept selling the game on Steam. This continued for about a month when negative publicity and bad reviews caused Ubisoft to pull the game off Steam. The fact that Steam just let it drag out until the publisher did something implies that Steam doesn't have a problem with things like this. Ubisoft isn't some off everyone's radar indie publisher that nobody is watching.
If you don't want to agree to that, you can always not purchase games from Steam at all.
