Inch by Inch isn't VR, but god it was VERY effective for me. I... struggled to play this game without just shivering and watching myself shrink.
Size Matters copied Inch by Inch and expanded on it, adding all sorts of features from the look of it. I don't know if they're planning to add VR support or not, but it'd be a really good idea if they did.
I wonder how hard it'd be to mod them for VR support anyway... because they'd be perfect for it.
