I didn't get to work on an experimental gameplay type project as I'd hoped this holiday break. However, I did get a ton of stuff done that I'd been putting off for quite some time - and that's fantastic!
I borrowed a copy of Rules of Play today that I'm finally going to read after much recommendation. Also, I grabbed a book on architecture for my little city generator side-project. Maybe I should check out this as well. Speaking of which, perhaps I'll meet Will Wright one of these days since we work for the same company and all.
I got Gears of War and Marvel: Ultimate Alliance for the 360 for Christmas, both of which are great!
