A few days ago, I installed "Serious Sam: The Second Encounter," a game I haven't played for many years. Released back in 2002, SS:TSE is an incredibly fun first person shooter. Though the graphics are dated, the gameplay is as fresh and exciting as ever. If anything, playing this game makes me even more excited for the Serious Sam HD remake that's coming soon.

What really surprises me, however, is how much I remember about the game. It's astonishing how, after all these years of having not played Serious Sam, I remember the location of nearly every secret area. I can remember areas where enemies pop up unexpectedly (so I know to be on my guard), and I remember most of the various ammo and health drop locations.

If I were to load up Wolfenstein 3D, I could probably take you to 80% of the secrets in the first chapter of that game. The same thing holds true for Doom, Duke Nukem 3D, and countless other titles that I spent time with when I was younger. Have I really wasted that many brain cells to remember stupid things like this?
