Electronic Arts did not pull Crysis 2 from Steam, it was kicked out by new Steam regulations.
EA has moved to clarify the situation surround the sudden and unexpected removal of Crysis 2 from Valve's digital download service. Speculation suggested that EA had pulled the title in order to make it exclusive to its own new digital service, Origin.
But this wasn't the case, as EA has explained: "It's unfortunate that Steam has removed Crysis 2 from their service. This was not an EA decision or the result of any action by EA."
The rep added: "Steam has imposed a set of business terms for developers hoping to sell content on that service - many of which are not imposed by other online game services. Unfortunately, Crytek has an agreement with another download service which violates the new rules from Steam and resulted in its expulsion of Crysis 2 from Steam."
"Crysis 2 continues to be available on several other download services including GameStop, Amazon, Origin.com and more."
It sounds like those Steam regulations are demanding increased exclusivity of some form. If this is the case, could a number of other games available on other download services follow suit?
