I assume you're all against gay marriage, then? Because both positions are countered with "how does other people doing things in the privacy of their homes that you wouldn't do hurt you?" Is there some abstract "sanctity" of games that non-gamers would be violating by playing games in a way they're not supposed to, even though gamers themselves are just as guilty if not more of violating that sanctity it in their own ways by cheating and hacking and using walkthroughs? The parallels are striking.
I say let people play games the way they want. It's an option, one that can be used or not used at each individual's discretion. You can play the game exactly as if there were no demo mode if that's what you want. Again, if this is successful, it means games don't have to be dumbed down anymore -- they can make a full game, catered to us, that can dumb itself down on the fly if needed. The market needs to be expanded, Nintendo needs to make money, games need to sell to bigger audiences to justify making them, and this seems to potentially be about the best possible outcome for us in this situation. Because the other option is for them to just completely abandon us and do nothing but sell so-called "non-games" to the 95% of the world that's not us.
Don't talk about the way we "should have to" play games or what we're "supposed to" do. Going back to the gay marriage comparison, whether you agree with them or not, Christians can claim that the word of God supports their positions on what we should do, and that it's not just a personal preference or opinion. The closest thing gamers have to God is Miyamoto, and he's the one doing this.
You don't get anything for letting CPs fight themselves in Smash Bros.
What do you "get" for beating a platformer? All I've ever gotten is the satisfaction of knowing that I beat it. You don't get that from having the game play itself. It'd be one thing if they were getting some kind of achievement points for it or whatever, but I'm pretty sure the patent specifically says that when you use it you won't be able to save and things like your score won't count.
For the record, I'd rather government didn't have anything to do with marriage at all, seeing as it's supposed to be a religious institution, but that's not really relevant right now.
