Name the first video game map that pops into your head.

Blood Gulch

Salamun Market

Nuketown...

Um, anyway Core from Crysis >_>

The overhead map for Wind Waker.....*shrug* fuck if I know either.

osamas compound

Compound, Timesplitters.

Gridlock - Gears of War series

Crash from CoD4.

Metroid, the original area.

2 Fort

Don't know why, don't even play TF anymore...

Vice City 4 Lyfe!!!

SMB3 last world map, which looks like Hell... in a good way XD

The Witcher 2

The Citadel from Mass Effect. 

I had several actual maps pop up in my head first, but "Lost Temple" was the first map with a name that popped up.  The rest might have names, but I never learned them.

Lost Temple, StarCraft specifically.

" Foundry - Halo 3. Man the times I've had with custom games on that map. "

Laguna Presa, BFBC2

Sword Base from Halo Reach

First one to pop in my mind was Blood Gulch(pretty iconic), but my favorite map would have to be Liberty City(It's just so fun to roam around in).

2Fort, Team Fortress Classic version to be precise.
