I've been playing the original Half-life and its expansions (blue-shift and opposing-force) recently. I really enjoy the way the expansion packs tie in with the original game.
For example, at the start of Blue-shift, you are stood outside a door and Freeman goes past in the rail car. When you play the vanilla game, you see that security guard stood there.
Also, in Opposing force, you hear one of the soliders mention they are commensing bombing runs. Again in the original, you are caught in the middle of that bombing run.
I just injouy things like that, that tie the different perspectives together.
