It's also without a doubt the most classic, textbook symmetrical layout to a map gears can have. They've evolved it throughout each sequel with a different setting which always keeps it fresh. Gridlock's a map that was with us in the beginning, it fostered our initial interest into the series and has that nostalgic effect each time it comes in rotation. Out of the 4 people that have commented i'm surprised it hasn't been mentioned! Gridlock is an absolute classic that deserves to be on everyones list. I don't have a top 10 list but i'll be honest here.
