OK, here is what I am thinking as long as if you beat the game on easy it has the same ending. I will run through it on the easy setting. Dose anyone know if it still provides the full story and best ending?

I hate it when they give separate ending for the time or difficult the game was beaten in. Damn you Metroid (first game that pulled that shit).

If I were you I'd play it. It's amazing.

There's no difference in endings or any kind of story related content between difficulties. Just how tough the enemies are, and how fragile your character is.

So I would just be looking at achievement point differances then... cool thanks all.

I would say it's worth it just to play Gears of War since it's a really good game.

The game didn't become and instant hit for no reason...

awsome point... I am playing it.  Sleep is for the weak right, who needs it?

If you can beat it with a friend, its a blast. If you cant dont worry, just read the story synopsis on wikipedia.

Just finished my playthrough. Surprisingly, there were a lot of little things that I really didn't pay attention to (like Dom saying "I'm looking for someone", and citizens telling him "no luck finding your woman") that apparently have lot of backstory. I guess Gears 1 was just a teaser for Gears 2!

Play through the first one it is fucking amazing plus you will catch up on plot points.

I'd agree with this; find an online buddy and play through campaign mode.  Fun for all!
