I own the original game but am not a huge player right now. My computer hates to load it in less than 10 minutes, so my ADHD won't let me play more than two missions in a row before I jump off to something else.

However the expansion adds one my favorite 'mechs, the Crab, and I heard it did some interesting parts to some of the game.

I was just wondering if it does it all to the end-game, or if there were enough early and mid game content that I might want to pick it up for the hell of it.
