This
Crysis 2 Product Page on EA.com has a link to
the game on Origin using a "buy now" button that says "only on Origin." In keeping with that there is a discussion on the
Steam Users' Forums about how the first-person shooter sequel is no longer available on Valve's online service. On the other hand, as noted
in sflufan's NeoGAF post, as of this writing the game is still for digital distribution on
Amazon,
Direct2Drive,
GamersGate, and
Impulse, so we'll have to keep an eye on them. It is also noted that
Alice: Madness Returns is likewise not available on
Steam, but is on other services, so perhaps there's some sort of Steam/Origins turf war brewing. Thanks nin via
