This is a living room game no one wants to huddle around a pc monitor with large controllers to try and play GH
Gee, haven't heard that one before. What's the average size of a monitor these days, 24"? Size keeps going up, price keeps going down. If you really can't see, I'd say your eyesight is a far bigger concern, and let's not forget that just about any TV screen you could buy these days will take a VGA or DVI input.
I really don't understand it at all - it is dance dance revolution with a different controller
Oh the voice of experience. Nothing quite like informed comments being made on actually having played something.
You might think it's crap, but try giving it a go. Only, Rock Band, not Guitar Hero. You might be surprised, but you have to be just a little open-minded. A little difficult, perhaps, but not impossible.
The reason I'm so for PC-versions of this game is that they should hopefully prove to be far more modifiable. That and, with any luck, both 360 and PS3 versions of either Guitar Hero or Rock Band hardware might work on it, which would be a huge plus.
