What exactly are you claiming it to be a ripoff of?
And by the by, your evidence sucks. Shit-tons of games have double jumps, gore has been a major component of gaming since Mortal Kombat first had twelve ribcages fly out of one human body, almost all combat games attempt to introduce a combo system, and combat is, well, combat. QTE and tits are so ubiquitous that you can find them in kids games nowadays. Now if you were just saying how sick you were of the flood of games based on The Divine Comedy, that's one thing and I'd support you. But as such you haven't given anything to support yourself.
Whats worse is you contradict your own argument! You list all these generic elements from games and say how bad Dante's Inferno is (not that I disagree, of course) because of them, then turn around and say mass effect is awesome because of its generic pieces. I'd also like to point out that SotC is only really visually different from ICO, Portal is just a Half-Life 2 mod (albeit a cool one), and Banjo-Kazooie, as epic and wonderful and awesome as it was really just took Mario 64, repainted it, and added a few extra features. Its just that the extra experience POLISHED the 3d platformer style and so it was more fun then its first incarnation.
But yes, Dante's Inferno sucks. Burn it, Bayonetta, and the rest!
