maybe that title is confusing, but my basic idea here is for everyone to list great features in games that seem to have gone unnoticed by many gamers.

I'll go first:

1. Call of Duty 4  in Arcade Mode there is an extra board called The Mile High Club it's a nice short board and perfect for arcade score type challange, but I'm amazed at how few people have logged their score on the leaderboard it seems most people beat the game and went straight to multiplayer.

2. Orange Box's Developer's Commentary, A brilliant mode available on every level you beat in the game. Valve has brilliant level/art design so getting to replay the game with little quote bubbles that when hit give you an interesting perspective on the design of that area has added tremendous replay value, yet most people I talked to have ignored this option.

 All right please add to the list, even if it's not in 2007 there some great things we are missing in games we already own!!!

Wow I can't believe I didn't get a single post here. I guess I should have bashed a system in my title.

yeah u should have

I have one:
In Lair, a horrible PS3 game (I should know, I have it) you have the option to play the game on remote play.

Ooops

 What is remote play?

@Fooflexible

Remote play? Using your ps3 and most of its features anywhere on the planet using a handheld(psp).

I like the bonus shooting gallery side quest in Resident Evil 4. It helps break up the tension between levels.

I remember I read that when you get 121 stars in Galaxy you can go somewhere and you can see how many times you died throughout the game.

There a feature.
