I'm a collector of video game memorabilia and I've been looking for a unopened copy of the original Guitar hero for PS2. I found one for pretty cheap online, but it's called "Guitar Hero Hard Rock Cafe 35 Years Bundle" . As far as I can tell the only difference is it doesn't have the official license product hologram on the box and a big white sticker with Hard Rock Cafe on it. Is there anyone here wise enough, maybe Harmonix staff, that can shed some light on this? Is this the exact same bundle as the original but a promotional release that was mass produced later on?
