Sorry Harv, if those titles are your idea of "good quality", You'd probably self destruct if you actually played anything that was credible, and not just shovelware/cash-ins on franchises.
None of those titles can in any way be deemed shovelware. Ninja Gaiden 3 for the U is practically a new game after the developers have fixed the vast majority of problems with the PS3 and 360 clusterfucks. Any Lego game, and any sequel to any game, should be considered a 'cash-in'...it's a new addition of a popular franchise and having a Lego GTA is going to be instantly full of win with toppings of Awesome Sauce.
Rayman Legends shovelware? Or a cash-in..? Then so was Rayman Origins. Like Lego City Undercover it's a new installment of a popular franchise. There are talks of it being a timed exclusive, so if that happens and it's released on the other platforms then does it stop being a shovelware/cash-in title just because it's released on your platform of choice..?
Monster Hunter..? Again, it's a new installment of a successful franchise and despite it's roots from the original title on the Wii should be considered a GOTY equivalent. No more of a cash-in than any other GOTY Edition of any other franchise and definitely not shovelware by any stretch of the imagination.
Scribblenauts Unlimited, again, can't be considered shovelware or a cash-in. It's the first time that it's appeared on a home console and going by the user feedback and reviews it's a top quality title.
Aliens Colonial Marines is a multiplatform title with the U SKU having enhanced eye candy and gameplay thanks to the U's power and controller and in no way should it be considered shovelware or a cash-in unless you want to tar the other SKUs with the same brush.
