Once they add a option to skip/autoplay the predictable-outcome fighting sequences I would buy any sequel. Seriously if you're over 30 you shouldn't have to prove to anyone anymore that you can beat scripted hoards and boss fights.
Some goes for Spec Ops: The Line after playing the first two levels I preferred watching the play-through on youtube over having to kill the equivalent of whole population Staten Island one by one just to follow better than average plot.
Also what Dara Ó Briain says:
"I love video games for this reason over all other art form. They do a thing that no other art form does, right. No other art form does.
You cannot be bad at watching a movie. You cannot be bad at listening to an album. But you can be bad at playing a video game, and the video game will punish you, and deny you access to the rest of the video game.
No other art form does this. You’ve never read a book and 3 chapters in, the book has gone, “What are the major themes of the book so far?”
You go “I, I, I don’t know, I wasn’t paying close enough att…”
And the book goes THOOMP."
