The Convoluted World of DRM
You have to love this: Valve hasn't added the latest Ubisoft games to their UK store (although they have arrived on the US side) - supposedly due to the "always connected" requirement of Ubisoft's latest games. The amusing part of that is that Steam requires either a constant connection or unsafe credentials handling in order to play - makes me wonder whether the combined DRM schemes are somehow causing grief.
In any event, this is the perfect example of where DRM gets you - problems for customers, service issues for the vendor, and unforseen complications due to unplanned software interactions. Awesome, isn't it?
