These aren't in any specific order (other than what came to mind first and last).
1. When you are playing a portable RPG in a car and you're half-way through a LONG boss fight that you're winning and notice that your battery is dying.
2. Using literally EVERY resource available trying to open a door in the ice cavern on Ocarina of Time only to find out that you just walk up to it and press A.
3. Playing Halo 3 for the first (and last) time.
4. Beating Limbo only to find out that [spoilers that I won't reveal].
5. Playing through Kingdom Hearts Birth by Sleep on max difficulty and FINALLY beating Terra's last story boss only to accidentally overwrite my Terra file when I started as Aqua.
6. Losing ALL of my lives on level 1-1 on Super Mario Bros. 3.
7. patiently waiting for and buying Final Fantasy XIII only to have it glitch on the tutorial boss and freeze everything except the stationary animations and the camera.
8. Spending 2 straight weeks catching all 493 Pokemon on Pearl and then trading in the game 1 month later for Platinum and not realizing my mistake until I beat Platinum.
9. Losing over and over to the final boss(es) (seriously, there's like a bagillion forms) in Kingdom Hearts and not being able to skip the cutscenes each time.
10. Playing through Final Fantasy IV on SNES and making it to the final boss, saving, and going to bed, only to wake up the next morning to find out my cartridge decided to erase all of the data.
