The first day of GDC concluded with a very interesting trend. I have seen the social game tutorials and summits fill up, with around 400 people listening to industry leaders talk ab out social games. That is is a big change from the last GDC where there were social games summits but nothing quite this big. Also I have been able to talk to someone from the Microsoft lobby who explained that Silverlight and XNA will initially not mixable in the same mobile 7 application. Today I will be doing the Microsoft Developer Days tutorial and hopefully learn alot about XNA 4.0 and how it will work across all three platforms.
