I am trying to beat Paper Mario The Thousand-Year Door. Childish I know. But I never beat it as a little kid when I got it. What are you trying to beat?
I've been buying old games I was never able to finish as a kid. I bought Capcom Arcade Classics and, even with infinite continues, I cannot beat Ghosts and Goblins.
I bought Super Mario Bros. for the Wii can I still, to this day, cannot get past Stage 8-3 (where the hammer brothers are). I have friends that played video games casually that said they beat Super Mario Bros., which really puts my gaming skills to shame haha.
