You forgot to say it's 3D too!!
I think if you cound "colleting things" as copying every games would be "like" a Pac Man clone in that sense
As for upgrades or weapons taken from the boss you fight, that would be coming from the very first Mega Man (maybe there are earlier examples, but this is the first game I recall that mecanic from).
For the rooftop thing, I am not sure if you are serious... but hey, both games also go on and off the rooftops! so it's even more of the same after all!
first DLC will be: an option to remove the Infamous skin over Mario sunshine, it will reveal that not only the game is a ripoff, they just changed the textures!
