Nothing. Both are mediocre games so it doesn't matter.
Allow me to reciprocate
Anyway both games are mediocre. Nothing special about them. Might be the lack of the story, but I couldn't get into them. And no, they aren't "hard". Just frustrating. You know what's hard? Super Meat Boy. Or Max Payne 3 on New York Minute Hardcore.
So where in the world's the forgotten? Like soldiers from a long lost war We share the scars from our abandon, And what we remember becomes folklore
