Yep, my Dad (who is 61) bought Guitar Hero III for the PS2! I was visiting my parents for Christmas and took my little PS2 with me to keep me entertained when I had nothing to do (notched up 70+ hours on Final Fantasy XII), when one day my Dad says he wants to get Guitar Hero III, yeah yeah I thought, then one day I mentioned Blockbusters might have it jokingly. Next thing he goes in and buys it! This is not as a present but for himself

Thing is he doesn't have a PS2, but luckily I have both a fat and a thin PS2 so I've given him the fat one. I guess this proves that you're never too old to get into gaming
Having never played any of these games before I thought I'd check it out, and unlocked some songs for my Dad to practice with while I was at it. It was enjoyable but I found it way too hard on the most difficult setting, I was all over the place and barely hit the right notes.
