Yeah!
And it'll never fucking happen because Ubisoft can't write!
FUCK YEshit

Yup, UBISOFT is pretty crappy when it comes to original ideas.

Asscreed was basically a Prince of Persia redo, and Prince of Persia was a franchise revival.

I gotta say I really did love the PS2-era Prince of Persia titles too
...Well, okay, really just Sands of Time and certain segments of Two Thrones
But I guess the gameplay in Warrior Within was also nice

Sands of Time was pretty radically different from the past game, though. More like a franchise reboot on par with Syndicate, except at least they are both platformers.

Also as someone mentioned I can't believe they would let WWII pass by without it being a Templar/Assassin conflict behind the scenes so I would expect a game set in that era at some point (even if it were another person's genetic memories).

As for a modern-setting Assassin's Creed game, as mentioned the uniform would change, and they would probably make it have futuristic gear, like the cloak turns invisible, you have unmanned drone weapons, magnet boots that let you walk on the ceiling, that kind of thing, where Desmond is assassinating people in a near-future environment.

I want to assassinate Hitler!

Gotta be honest here, i see they using WW1 more than WW2... i mean, the can get away with the whole "Close Combat Vs Gun" scenarion on 3 because on that era firearms were still full of problems. But when WW2 comes around... really, the only way to pull a decent AC game there is to pull a full on Splinter cell stealth game...

a couple of errand, slow charging, bad aiming Muskets i can see an assassin overpowering... but a small group of Military soldiers with Machine guns and grenades? No way.

We convince him to shoot himself ala Mass Effect 1's end, Fallout.
