Overplayed? What recent game in years has had ninjas in it?
Mark of the Ninja. That's about it. Everything else short of Tenchu had 'ninja flavored' elements where the dudes just showed up with their faces covered, jumped 10 feet, swung a katana and called it a day.
This would be piff if done correctly, but Ubisoft and the makers of Asscreed prefer to just build a framework, copy and paste and exploit that shyt until the wheels fall off like they did with Assasin's creed, they ain't gonna wanna risk making a new IP and not have it turn over a healthy profit off the jump and while I don't blame 'em from a business standpoint, they've a habit of releasing blatantly broken games and patching them after the cash has been counted. fukk 'em, I'd rather see a new Tenchu at this point.
