SC 2 is a NEW story with no boundaries. THIS is a far more apt example:
-Based on a single book.
-Split into 3 movies.
-Added "content" to make it 3 "full movies"
Worked out fine enough, right? This is what will happen. Mostly stupid new shit no one wants to see. Genesis added into the main story etc
This is the shit I'm sick of seeing. No, this is not what WILL happen. This is what MAY happen. You know what else might happen? It might be fleshed out and wonderful.
It has the potential to be shit, but it has the potential to be great. The fact that you are writing this game off when we've seen like 10 seconds of gameplay and a few interviews shows how little imagination you have.
