I wouldn't let the skill ceiling sway you away from the game.
I played on the easy mode with no aim assists and the game was a blast.
There are also multiple assists (aside from changing the difficulty) that allow for people of all skill levels to enjoy the game.
Just a heads up! Don't want you to miss out on this awesome game because you think you'll be bad at it.
LOL. Well, my PS3 is still in transit (moving to a new house) so I won't be able to play it yet. Thanks for the heads-up, though.
