And here we go ...
Definitely not buying ...
Now, again, the difference between Steam and Origin:
Steam's EULA doesn't tell you specifically WHAT they collect, but what they DO with it.
Origin's EULA does tell you what they collect ... but not what they do with it ...
Difference between LIVE and Origin in regards to yet-another-service-other-than-Steam:
LIVE is implanted in the game directly, installed all along, hardly requires data to be entered, and belongs to the company that already supplied your goddamn OS ... Why on Earth would you even bother hiding anything from them when they could implant anything they want into your OS - and you'd mostly be forced to use it regardless, if you want to play most games conveniently.
Origin on the other hand requires a whole external account, at a company that supplies said games only, requires an external client installed and run independantly - or requires the game to be run through this client.
As such Origin is an intrusive, restricting, annoying and pretty much useless service.
