Super Mario bros 1-1
Every first level of any sonic game.
every first level on every sonic game i've currently played. my favourite in particular being the one from Sonic Adventure 2. best opening level i've ever played.
i'm also fond of the level on Harvest moon... that thingy majig one.. you know, where you don't farm and you stop playing and live a normal life. yeah, i quite like that one. Its much better then the current level i'm in, having repercussions in real-life, desperatly wanting the game but knowing that it will only hurt me more the closer i get.
fighting sin and entering its mouth, i'd also include "inside of sin" as part of the level too. all within in FFX. mainly the first area, where you battle up and reach Seymour Guado (who somehow ended up inside of sin, being the awesome beast who won't die that he is). Mainly just for the music in the final battle against Seymour, but also because of how awesome and hard the game suddenly becomes as you rush up head-first against (supposedly) the biggest threat in all of FFX-land (i forgot the name... Spira! i remembered now -_-)
Resident evil 4, i'm very fond of the level where you fight two of the Garganta at once, just because fighting them both is quite fun. i always try to not trap them in the molten metal pit, because then i don't get the money for the kill -_-
