I will not be buying Civ5. Nor will I steal (pirate) it. I take a firm stance on the protection of IP rights. But I'd be more likely to steal Civ5 than to purchase it. Upon install of a purchased copy, steam takes away the users ownership rights. I'd have more confidence of ownership, by stealing the damn game than I would by buying it! So Civ5 is dead to me. It's all about Elemental now baby!!!
It is a tough situation for conscientious consumers in the game industry lately. Quite a few newer titles are getting away from the "consumer ownership" style, traditional purchase model, and going toward the "consumer license" marketing scheme (scam). No longer to you pay money and purchase a box of software for your own use, as you see fit. Now you "license" the use of game software for use only in specific fashions laid out in the EULA (and on the box) and have limited technical rights to your purchase.
Added to that, companies throw in online DRM to use games even in single player mode ... which, if you dig through your EULA, there will be a clause about your "purchase" discussing what happens if the servers go down (temporarily or permanently - Hint: You are screwed out of your "purchase") which does nothing to stop actual gaming Pirate groups. All these DRM measures do is make more hurdles and hoops for paying customers to go through, some of which people can (and do) easily argue, take away your previously accepted rights as a game consumer.
Trouble is, most people dismiss arguments against DRM as either "well you are a pirate then"; or "well you are paranoid."
Personally, I'm just pretty hard-line on people removing rights from me, to do what I feel I want to, with something I just purchased. I haven't had to call and "check in" since I lived at home with my parents ... why should I have to "check in" with a game company to be allowed the privilege of playing a game that I just gave them money for? Would you be ok having to connect to the internet and verify your purchase every time you want to watch a movie you just bought on BluRay? What if you want to put a few DVDs in your laptop case when you go on vacation, to watch on the beach somewhere one night ... should you have to ask permission to watch each DVD before you go somewhere that might not have WiFi access?
I hate any DRM that forces me to do, well, anything beyond registering my product to get updates (and I'm not too much of a fan of that, simply because hiccups can happen and things can suddenly stop working correctly - as seen with the issue of fan-made Elemental bugfix patches causing the game to stop working and give the spinny frowny face), or for older games that stop getting constant support. I usually find most up-to-date patches on sites other than the game company's site, either because they went out of business or no longer devote space on their website to ancient games I just felt like dragging off my shelf.
"Well I keep steam up 24/7, so I don't know why you complain" arguments? Well, I have Steam too ... got in a few months ago and purchased a couple games through it. Know how often I have Steam up? Only to play those games, then I shut it right back off. I don't want anything running on my PC unless I give it permission, I'm OCD like that.
I'm the person that downloads no-CD cracks for the games I purchase, just so I can load them on a laptop and not have to drag around 20 CDs in case I want to play any of the games I own, or if I want to put them in a box in the closet and not have to wade in there every time I boot up an old game that I forgot had CD requirements.
I'm looking forward to Civ V ... I'll probably get it off the shelf when I buy it (especially since there is usually no discount for D2D-style purchases compared to B&M shelf purchases - so I might as well get something physical for my money), and I'll probably break it so it doesn't require a check-in to play single-player (which of course is against the EULA, but I'm evil I guess).
Starcraft II has the same-style DRM as Civ V seems to ... you have to "check in" once in a while to verify your account to play single player. Know how many days it took the pirates to release a working copy that subverts that mechanism? -1 ... negative one days ... there were working copies of the single player game the day before release. Paying customers have to deal with stupid hoops, yet the people stealing the game not only get it for free, but they don't have to be annoyed by stupid restrictions like we do. The industry has lost its mind.
Edit: Oh, and for the sake of full disclosure ... I am paranoid. I don't even post using the same account, or even email address, that I make my game purchases through. A long while back I made some criticism posts in a beta forum for a game I was helping test, and they revoked/banned me from playing further. So ... paranoid. ... but that still doesn't make my comments any less true
