This can hardly be called a stealth game; especially given Altair's ridiculous proclivity for getting in massive, unavoidable swordfights, be it just getting from one end of town to another or in the late game assassinations.
Which are inherently ridiculous from a story standpoint anyway. Real secretive stealthy assassin types just soldier in where their targets are expecting them and battle a dozen guards and archers. *Eye rolls*
But I wouldn't have a problem with that usually. Yes, it weakens one of gaming's stronger narratives (A relativist-style narrative with a whole LOAD of cliches I find annoying in other stories, but far better told than certain RPGs *CoughKOTOR2Cough*), but again, it is a video game. I can deal with that. What DOES annoy me is that Altair controls like a drunken shopping cart in navigating tight spaces while being pursued. Sam Fisher, Garrett... hell, even Solid Snake and the Tenchu Ninjas could sneak circles around this clown. And not a one of them handled so poorly in combat situations.
Okay, I'll give you the Tenchu buffoons and MAYBE Sam Fisher on a really bad day.
...
Alright, Snake too. But he could at least perform somewhat reliably... you just needed eight fingers to hold down all the buttons necessary to get him to do the job.
