Haha, they even have a TMNT demo in that list, but no Rise of the Ronin. By the way, the combat animations in RotR look excellent from what I've seen. It's on my wishlist, but will likely be awhile before I get it. It looks like the kind of combat I usually enjoy.
Its pretty easy too on its easiest difficulty and on its hardest, really only hard when you have to fight someone 1v1 (at least for me) and those are if you seek out those individuals, most boss fights you have 2 others on your team you can switch to, which is recommended to win those and its fun.
The 1v1s (so far)really only give you gear and arent main-story questlines or even apart of 100%-iing an area. So those fights really are the only part that gets dark-souls like with fighting, but everything else is more
ninja-gaiden/ac shadows and is fun and open to run around (albeit kind of baron) and assassinate, glide, horseback ride, find and collect cats, whatever lol, and if you build up bullet damage enough, you can 1-shot enemies even at the highest difficulty. So its pretty interesting in that regard.
Theres also a gta-style cop system where you can kill civilians and pickpocket them but after a while youll have all the guard after you. Its fun and can add a pretty good challenge combat wise.
Since its release, there have been a couple patches so its a lot more stable now im reading too. Its also 50 as its main release, so def. check it out on sale when itll probably go for 20-30 which i would pay for personally. It has its issues (like you cant exit the game from the option of "quit game", it just takes you back to the main menu where you then can quit) and some minor bugs during combat. Its a KOEI/ Team Ninja game afterall.
Absolutely deserves to be on that list though.
