More to the point, why is it necessary to become so complicated? And do all the features actually improve gaming?
The short answers: it isn't and it doesn't.
I think Nintendo and Sony/Microsoft often try to justify the existence of consoles beyond their original intended purpose because the industry is still trying to figure out what it wants to be. Is it a separate kind of entertainment or is it part of merely part of the macrocosm of entertainment? Nintendo wants it to be just videogaming. Sony and Microsoft want gaming to be part of all entertainment. We can see this in their approaches. That's why Nintendo keeps pitching new controllers. Their focus is on providing different kinds of play. They don't really want you to stop playing videogames. Sony and Microsoft pitch these all-in-one devices. They don't want you leaving the living room when you stop playing videogames. It's a subtle difference with very different results.
I, personally, prefer Nintendo's approach because I really don't need or want half the **** Sony and Microsoft include in their consoles. It didn't really bother me before because I could just ignore the extras I didn't care about. What's annoying (and kind of creepy) is that it's becoming more difficult to ignore those things because they're becoming more intrusive. Sony has a Share button on the Dual Shock 4. I don't want to fucking share anything. I just want to play videogames and without having to worry about accidentally telling everyone how awful I am at it, goddamit. And Kinect 2.0 was incredibly invasive before Microsoft backed off.
I feel like Online is the trojan horse for all things expendable. Yes there is true value in bringing gamers together to play against one another or together, but simply because the system can go online, does it have to bring every feature an online product can?
I like the idea of online gaming more than I actually engage in it. I simply prefer being in the same room as others for multiplayer games. I don't think online gaming, even with video chat, can ever simulate that. Communication has evolved so much in the last 15 years. It's pretty cool how far technology has come in that time though it's kind of silly what people have done with it when you think about what people share on Facebook, Tumblr, and Twitter.
People like the idea of a connected world. We've never had it before. And who can argue with the convenience? And we can connect with people who share our interests. That's something l really like about Miiverse on a videogame console. The communities are centered around the games. I don't need to know what you ate for lunch. Tell me about the stage you're stuck on. Again, not all of it is useful, but it is nice how much more focused it is.
Furthermore, innovations in gaming are rare these days. There are very few moments where something actually shocks me in the way its played. Does that dictate that more innovation is needed in how we interact with games? And are developers simply not able to expand genres or create new ones within a confined, traditional control scheme?
Well, does something need to shock you in order to be enjoyable? I think there's a delicate balance. Certainly, I don't want to play the same thing over and over again, but I don't think everything has to shatter my mind to the point where I'm barely the same person anymore. Innovation can come in all shapes and sizes. Nintendo has introduced brand new ways to control videogames. They've also created Z-targeting. Innovation depends on what a developer wants to accomplish and how much they're limited by technology (though not so much anymore), budget, and publishers.
Lastly, is it the experience of gaming that has become more complicated or is it the framework behind them? And if either, is there a way to make them simpler or are we forever on a path towards something more complicated?
Technology has dictated how much more complicated videogames have become simply because developers want to try out their new toys. We've come to a point where we can do so much already so we may be returning to ideas. Before developers had to work within limitations and creativity sprung by what they couldn't do. Today, there are so few limitations and since they can create just about anything, it's less about pushing the bar in terms of technology and more about pushing the bar in terms of creativity.
