Whiteblade999: Steam is DRM just like securom is DRM. Now what someone is willing to tolerate is completely different.
Steam locks the game to an account and loses the ability to resell but you get a free backup, community crap, nothing hidden is installed (you know about the datamining), has an offline mode and an easily cracked DRM which lets you make backups without Steam DRM easily.
Securom lets you resell the game, installs hidden crap on the PC, can stop someone from even starting the game (authentication servers going down for example), can refuse to run because it doesn't like specific hardware, is hard to remove in some cases because it isn't uniform like Steam, and needs a seperate installer to remove.
I'll lose the ability to resell my games if it means I don't have to deal with all the negatives Securom has. Now I want DRM-free but DRM is here to stay, so pick the scheme that fits your list of things you want the best or avoid any game with DRM.
I guess I still don't see the difference. SecuROM is crackable is it not? Steam is crackable. They both require activation. SecuROM may require a disk check depending on the publisher's choice. Steam can keep you from playing your game (even in offline mode) and so can SecuROM.
Ever since SecuROM added online activation I see very little difference between it and Steam, except Valve can screw an entire account with Steam, SecuROM can only hose you for a single game.
