I'm unsure. I haven't worn them yet, and I don't wear prescription glasses, so I don't know if they'd be a bother after 3 or 4 hours (I generally game for about that much at a time). I also heard they were battery powered, so how often do you need to change the batteries? I HATE changing batteries. My wireless mouse dies once every two months and I almost scream when it does (well, not really, but you get what I mean).
There's no option for unsure so I will not choose one. The price of said glasses and the tv's is not an issue since it's "Would you play games wearing 3D glasses?". Would I? I would definitely try it, game for as long as I can with them at a demo show or something. If I got a TV and glasses for free, I'd for sure try it. If I can do it comfortably, I'd keep gaming with them, yes.
TL;DR: If they're comfy, I would game like that, maybe not all the time but I would.
