Luigi's Purple Coins in Super Mario Galaxy
The Flood Level on Halo 3 (until I started killing those wall hugging creatures before they evolved)
Online Street Fighter II Turbo- If the guy you are matched up against is from Japan, RUN!!
Dead Rising -Brain Dead AI on people you're trying to rescue
Advance Wars DS- Often, I touch the screen in the wrong spot, and start a chain of events that cost me an easy victory.
That pretty much sums up 2007.
