To address your points:
1. True. I did think the bomb thing was kind of stupid. Just do what I thought with the trailer: make a thicker smoke bomb from the one before. Besides, I only used the splinter, smoke, and cherry and added from the weapon's dial. It's nice to have option, but this isn't option, it's fucking around with (mostly) useless shit.
2. Indeed, this mini-game blows. Sometimes I just let them win and kill the captain again, that part is kind of fun.
3. I like that it adds to your awareness, finally means if you do it too many times in a row and forget about it, you can become fully aware, it be somewhat tense to go through and get caught by guards. It is somewhat annoying, but I didn't see it as a flaw.
4. Not sure what you mean by the locations changes. I suppose you mean when you enter hidden tombs, search for keys, and when you go to kill the fat basterd that Talik was killed for supposedley being aliend with, right? Well, that's what it felt like in ACII to find the seals, or in brotherhood to get the Romulus keys. It feels normal to not feel normal in these sections. And in Brotherhood: Seemless? Not really, it was the exact same thing there, I really don't understand where you see a difference. If you speak, this ear shall remain listening.
5. Couldn't agree more, I hate the location. I hate the damn boring brown and too light gray everywhere, I prefer the beauty of Italia; Roma, Fierenza, Vieneza. I hated Jerusalum, Damascus, and here.
6. Mind expanding. Maybe my mind isn't that fresh, but I assume you mean when you start a mission then bullshit happens when you desyncronize immediatly. Yeah, it sucks, but I can get past that.
7. Of course Altair's sequences are short. This isn't his game anymore, this is Ezio's story. Merely bits of Altair's memoir to help the order not make the same split they did years ago. Besides, I like that their short. It means he doesn't over stay his welcome.
8. Indeed, these guys blow. I can't stand the jump scare with the music que, and they're only worth is the money you get from robbing their corpses. Not sure what you mean by snipers. You mean gunmen and bombers? Or something else. *shrugs*
9. Yes. Desmond's first person platforming sucks. But like Yahtzee said in Catherine "But as frustrating as the [block] puzzles were, they were never the kind of puzzles that made want to stop playing, or bang all of my expensive elctronic goods together. They just made me grip my controller harder, clench my teeth, and be all the more determined to get just one more level." Besides, I figured them out and loved the bits when he talked about his past. FINALLY!! I give two damns about the MAIN CHARACTER of the LAST 4 GAMES!!! [sarcasm] Great job developers and story tellers. [/sarcasm]
Overall, I like the game. Not the greatest ending of a trilogy (Ezio) or quadrilogy (Altair), but one I'm stasfied with. Is it perfect? No, nothing is. Is it great? That's in the eye of the beholder, but I think so. It's still fun, it's still good, it's still a great story. Overall: it's still Assassin's Creed. Can't wait for Assassin's Creed III. For those who don't now, as of right now it's been decided each game would be number by ancester. ACI (Altair), ACII (Ezio) ACIII (?) Seems it's going to be Desomnd, but who knows, besides Ubisoft.
