All you need to do is get to San Diego in the next four days.
Thanks to a tip from one of our readers, we've found out that Nintendo has a booth this year at the San Diego Comic-Con. Convention goers will have the opportunity to play two huge upcoming Nintendo Gamecube titles, Metroid Prime 2: Echoes and Resident Evil 4. Along with these titles there are also some Game Boy Advance demos.
Other companies, including Konami, EA, Activision, and THQ also have booths at the cons with demos of their games.
The San Diego International Comic Convention runs from July 22nd to the 25th and is being held at the San Diego Convention Center. Entry costs $60 for a four day pass, or anywhere between $15 and $30 for a single day (depending on which day it is).
