Yes, and there are also laptops that can handle it. It would be interesting to know which type of integrated graphics card can handle the game. I suppose the ATI Radeon Xpress 200M is unable to do it, perhaps Humvee256 can play "guinea pig"? No, probably not.
Game specifications indeed never (?) touch the question of laptops. It is of course understandable since most of them share the memory of the motherboard.
But instead of "specifications" for laptops, the members of the forum who can play SS2006+Addon on their laptop could tell it to everybody. Perhaps a topic on that question?
So, the question of accountability of the publisher is avoided, on a subject where there is no global solution?
Just a thought, of course.
