No More Heroes 2 could be really awesome if they:
-add more enemy varieties and scenarios
-drop the sandbox crap OR actually give it a reason to exist
-work on the graphics (though it was mostly bad in the sandbox city because of the atrocious LOD distance)
Seriously, I kept driving past that high school before it could actually transition to the higher-quality version. If you were at least 30 yards away it suddenly became a big blurry box.
