Mario and Luigi: Partners in Time.

I've played all the Mario and Luigi RPG's except for that one! I almost played it when I bought a recycled version from the local EB Games. Though, it didn't work. Kept getting error messages :(

I think I would say Snatcher or any game on the Adventure Vision.

final fantasy 7... but i think it is too late to adjust in their graphics now.

Ugh...this thread is so painful to read...you poor people, deprived of such incredible experiences. And for some of them, I share your pain. One of my biggest regrets in my gaming life was the day my mom went to Gamestop with me near the start of the Wii era, on my birthday, to buy the last of the used Gamecube games before they became hard to find. I got so many absolutely incredible games that day, but my mom was so generous, I began to feel guilty, and when she offered to get me Skies of Arcadia, I turned it down because I felt bad. Now I wish I hadn't, it's the number one title on Gamecube that I wish I could play that I haven't yet. Aside from that...Tales of Vesperia comes to mind as the main reason I want a 360, Kingdom Hearts: Birth By Sleep is the main reason I want a PSP, Psychonauts was the main reason I wanted the original Xbox, I've still never played The World Ends With You, can't find The Last Story anywhere, have never even owned a Sega system, have never finished a Mega Man game, have never finished a Final Fantasy that wasn't Crystal Chronicles (this one wasn't my fault, the universe is conspiring against me to prevent me from finishing one, I swear), and probably my biggest gaming sin, I have two versions of Majora's Mask but have finished neither.

No biggie! As long as the gameplay is still awesome, I will gladly play it!
