Yeah, Twin Snakes was a remake of MGS1. I've been keen to get it (the only game we have on GameCube is SSBM -- we got them together on eBay only a year or so ago), because in my last play-through I was disappointed by some gameplay flaws that I had just never remembered.

Valkyria Chronicles had a really good intro.

I'm surprised how many games don't have intros -- when you first start a game up it's great to have a video get you all excited about what's in your future, especially since the player is often quite limited at game start.
