The only one I was able to guess so far was "The Secret of Monkey Island" (although I only know it as "Monkey Island I") - but that one I guessed from the first screenshot! Shows my age I guess...

EDIT: Ok, in the meantime I also guessed Portal 2, GTA 3, Bioshock Infinite, and a few others. Now I'm hooked too :(

There were a few I was pretty clear on. Then I got to Call of Duty and I knew the series, but 6 guesses later and I still didn't get the right one. (Haven't played any since the original!)
