Homer teams excluded.
What is the most memorable regular season college football game that you've seen recently (limited to the 2000s)? Mine may be Auburn v. Florida 2006. Auburn scores 19 un-answered to win the game and be the only team to beat Florida in 06. Everything about that game was wild: the pre-game war eagle, the primetime crowd, and the stellar defensive execution on both sides of the ball.
A close second for me would be OSU at PSU in 2006. Another defensive battle where PSU only put up 195 yards. It was the battle between AJ Hawk and OSU's D vs. the PSU D consisting Hali, Dan Connor, and Paul Posluszny. The WhiteOut was alive and well in Happy Valley.
What are some of yours?
