The Hidden Blade Assassin's Creed in Depth

Hello fellow assassins!

I doubt more than like... 3 of you know me, if any of you, but I've visited YouTube videos of Ian and Stab many times. I've used them, and when I first played AC1, I thought it was just another game until I saw these vids. I was amazed, and it has now become my favorite video game series of all time (Previously Sands of Time). I've beaten AC1 and 2 with 100% completion (except for the DLC for II so I have like.. 96.5%) I do "parkour" in my free time (though I mostly like to climb stuff, and I'll only do the actual sprinting part if I'm trying to get away/catch someone.), so getting AC1 was because of the climbing mechanics (also the reason why Sands of Time series was so precious to me, more climbing). Basically, I have a particular interest to any game that has the following in perfect combination:

1) Melee/ swordfighting, limited to no projectiles.
2) Climbing/Parkour
3) Stealth mechanics (optional)
4) Lots and lots of side-stuff (more optional)
5) Story is VERY important

So uhh... I guess you guys are supposed to welcome me to your little forum brotherhood and what not.
LIVE BY THE CREED! *passes out*
