@MP_Ryan: That's actually one of the problems that I've had. When I test drove Origin with the ME3 demo, it took me three hours just to get in one multiplayer game at my university. When back home, I have notoriously slow, unstable internet. I can't switch to a new provider because they are literally the only game in town, unless I go to dial up. The other item that bothers me is the Consent to Collection and Use of Data section in their Origin EULA. I reread the Steam ToS, and they don't have anything that invasive in there. But like Fury said, that ship sailed a year ago.
@Sparda: I actually had a chance to test drive both Origin (ME3 demo) and UPlay (AC3 for free from GPU promotion). UPlay (and Digital River, by association) is probably the second most unfriendly software system I've ever used, second only to Mentor Graphics IC layout tools. I'd never use it regularly, but for a one-off purchase, I'd deal with it. But at least it worked. On the other hand, my experience with Origin has been that it's nearly non-functional. Despite playing the ME3 demo for several days, I could only connect to about four games total.
Speaking of crappy internet, I'm currently not at my university. My ISP just decided to eat this message.
