A few suggestions for upcoming video collaborations:

1 - Favorite code/most useful (i.e. Contra 30 lives) in a single game.

2 - One feature in a video game that totally destroyed what could have been an awesome game (i.e. Battletoads had an issue with this with 2 players, I can't remember it exactly atm).

3 - Best graphics you have ever seen for a game on that console (i.e. Batman Return of the Joker on NES or Super Mario World 2 on SNES).

4 - A game that pushed the system to the limit (i.e. Street Fighter Alpha 2 on SNES).

5 - A game that you were really looking forward to but turned out to be incredibly disappointing after it came out (i.e. Double Dragon on NES with its pathetic heart system and 1 player only, or X-Men vs. Street Fighter on PSX where you can't tag in the 2nd partner and there is a lot of slowdown and missing animation frames which ruins the intense gameplay).
