Huh? The gaming community has spent the last 10 years or so fighting to get games recognized as an art form and now you think that limiting expressive freedoms is a good idea just so copyright infringement doesn't happen?
One of the most impactful games I've ever played was a PS3 exclusive called "Heavy Rain"[0]. That game, while having several branching storylines that create vastly different endings, was basically an 8-hour long interactive movie. It is one of the best games I've ever played but I doubt I'll ever play it again. I'm certain that I would make most of the same choices and reach the exact same outcome.
Another recent game that I really enjoyed is called Firewatch[1]. It's basically a three-hour movie. I don't even think it has different outcomes. You experience the story they give you.
That game was excellent (though really short for being $15). That sort of game would not exist in your worldview.
I watch Let's Plays almost exclusively as my digital content of choice. I first discovered Firewatch through an early pre-release copy that Marbozir played[2]. Luckily his pre-release copy only took you through the first 45 minutes or so and I was able to enjoy the full game on my own. Despite enjoying the game, the first 45 minutes of my game was incredibly dull because I'd already seen it played. Had I watched a full Marbozir playthrough, I would have probably never purchased the game. Without giving away any spoilers, once you've seen the whole game, there's really nothing left to experience.
I'm really torn about this article. I'm a game developer myself, so I definitely want to encourage people to buy games and support developers, but I have a family and rarely find enough time to actually play games. I get all of my enjoyment in late-night Let's Play sessions. This is a really tricky problem to solve, and I think being dismissive of a genre is dangerous ground to tread.
Thanks for your comment, though.
