1- I do not buy games with system limits, install limits, online activation and tend to avoid games with DRM that will disable the game(s) if a vertual drive is detected (such as alcohol 120) or open security holes for hackers. Revoke tools from install limits are of no help as internet access is required not to mention the hassle of this if it becomes main stream. Steam is the major exception, MP games like TF2 are fine but I try and avoid buying any SP games from them. Steam also offers very useful services such as easy updates and the ability to download & install a game as well as no CD's, they do however put 3rd party DRM such as TAGS on some games such as X3: Terran Conflict, which I refuse to buy.
2- DRM that does not overly inconvenience me, require internet access (except for MP of course) or open security holes. I must also be able to install it as many times on as many "machines" as I wish and not have to worry that if the company that made the game goes under I will not be able to install the game again. End result is the DRM should be invisible to the paying consumer, unlike today's DRM which makes a pirated version of the game (even if you bought it) a superior option (no CD's, no CD key, no security holes from DRM, no bugs caused by said DRM, no install limits, no online activation, no system limits) unless you wish to play MP, which can be worked around.
3- Some people are idiots. Some will look at what I posted above and go on about how internet access is not a problem as I'm on the internet now. They will not care about the reasons for my concerns, just that they have internet access, I'm using the internet right now so I'm full of s***. Some people never reinstall windows and don't even know this counts as a new system (along with hardware changes), I however can burn up a 5 system limit in a week between my desktop and gaming laptop. They say wait for the revoke tool (which so far one company has refused to offer for their game IIRC) which may never come, or call tech support that can chose to call me a pirate and ignore me. Others like one of my RL friends simply doesn't care about DRM and all the hoops he has to jump through, yet get angry when their computer starts screwing up after installing many games with TAGS & securom, frustrated trying to get a game to work when his wireless router is down (online activation) and gets upset that that changing his video card will cost him his last install limit, but never would he think to blame the game for anything (even the last one). Yet here I am with my copy of Men of War, I install it, use my serial number to register for MP and never have another worry, all because I know this game doesn't have any DRM.
Oh and side note, I consider a total lack of DRM to be a big selling point for ease of use. I have also stopped impulse game buying, I now check online reviews and what DRM (or lack of) a game has before buying, this is mainly due to buying Bioshock with it's 3 install limit (which I never bothered finishing and gave to a friend so he wouldn't spend money on the game). If ever a 100% effective DRM solution comes about but screws me over like today's hostile DRM, then I will simply stop buying new games for the PC, consoles should catch up in 20 years.
and @ chizow, STFU. You spam these threads with regurgitated arguments over and over again, now any post I see with your name I skip because you have nothing new to add and any disagreements have be said over and over. A post here and there is fine, but after that you have nothing to add to the conversation.
