I've tackled Assassin's Creed: Brotherhood and Dragon Age: Origins.
Yes, I know that one of these games has been out for a long as hell time but I didn't have a 360 back then.
Dragon Age: Origins is alright, but after playing through the introductions (all of the origin stories) I found that night impossible to survive the origin stories without dying at least once (because enemies like to pin my character to the ground and rip his/her throat out and take away 3/4 of my character's health when they're only at 50%) and the interactions feel like you'd be better off talking to a cardboard cut-out, save when something happens like when a [spoiler spoil spoil spoiler spoil spoiler spoiler spoil] but even then it's not even worthwhile seeming to be attractive as an introduction. From there it's a rather linear game, where you become enacted into the Grey Wardens after going through a trial, and then continuing on into a battle against a boss fight that is incredibly (easy if you are a warrior or rogue, incredibly difficult if you are a mage [YES EVEN IF YOU HAVE SPELLS THAT STUN AND FREEZE BECAUSE THEY TAKE TOO LONG TO RECHARGE]) and then promptly all of the grey wardens (save your character and alistar) die. Ran through the rest of the game, enjoyed conversations, got a band of merry men and women within the next two hours of gameplay (which flew by pretty quick) and then was immediately bored up until the end, which I was excited, then bored again.
My review: Dragon Age: Origins is a pretty good game, but it's one I'd rather rent than buy. (haven't done the downloadable content yet btw)
Assassin's Creed: Brotherhood is brilliant in how it starts off. Wait, no, nevermind, it's almost the exact same as when you played Assassin's Creed 2, save that you escape from rome. However, what it contributes to storyline is amazing, in how it acts as an extension to its predecessor while not being the same droll game again. In the attack on your villa you lose all of your gear, thanks to Ezio's charismatic hips, and most of your gathering is either captured or murdered, save your mother and sister. Then, you are pulled out of the machine and as Desmond you help the other three get back into the mansion so you could hide in there away from the Templars. Congrats! This is the most excitement you'll ever get from playing as Desmond. After that, you can run around the villa, searching for artifacts (replace searching with stealing because all but one are inside of a building) and have mildly interesting conversations with the others. (Favorite line is when you look at the Ezio statue and go "What's a matter with you, Ezio?" and get a 'That's racist' and a follow-up of you saying 'You're racist!') You can also check not only your own, but everyone's emails (i'm figuring that everyone decided on the exact same password for some reason) and learn about stuff that so far hasn't been any useful information to the storyline other than pointing out that these NPC's are more than just characters. When you're back in the Animus, you go through an hour and a half tutorial via missions and once that is over the difficulty curves up. (if you didn't train in the animus for when it came to chases and races, you better do that asap since it tells you a ton of information the booklet decided to leave out) The 'secret' armor cache gimmick has carried over from AC2 but now it's the 'Treasure of Romulus' which is pretty sweet armor, and a dagger! It's the best armor of the game, so you're not really performing shop quests to unlock the other full sets of armor because you know that you only need to get enough to survive an army of attackers so you can counter-attack and dodge your way to victory. A few flaws to address: enemies no longer take their time to let you finish executing someone (which could be an improvement save that you can just keep holding RT and press X when they're in the middle of their attack and you'll still counter them) and until you get the Leonardo invention that is just a metal glove with plated scales on the back you can't grab onto ledges, or jump up and grab onto another ledge, or attempt to grab a ledge when you get shot with an arrow. Weapons are severly limited starting off, and you need to purchase every single one instead of picking up a nice looking sword and taking it with you on your trip until the end of the level. That and ledge detection has been screwed up again, where if you were trying to run away from a pack of guards and you try to jump a bit to the right onto a ledge, but there's a haystack just tot he left, you'll do a leap of faith into the haystack. this wouldn't be so bad if the AI can see you through walls a good 30% of the time (which has torn through my patience when playing the 'cannot be detected' missions, which there are TONS to do, and they are mandatory) and running around a corner will no longer break line-of-sight from an enemy who is chasing you, so you have to run around a corner, do some parkour, grab a lamp and swing around another corner, and THEN jump into a haystack or rooftop garden. Then again, when you've gotten good enough at staying alive in combat, and your time isn't pressed, you can just kill the guards who spotted you, even if you have twenty on you, because you can start a kill chain by either: A. Countering and then pressing X while holding a direction. or B. Rappidly press X until you automatically perform an execution (because they took out the timing mechanism, and turned it into 'SPAM ATTACK NAOW!')
The good parts of the game would be when the storyline and missions go alright, as well as having a secondary challenge such as completing a level within 8 minutes or by not swimming, which helps those who feel like they are being suffocated with easiness. However, in later missions, such as after you get the Apple of Eden, you are to kill a large group of guards. The first time, I couldn't kill the last guard because he was cowering in fear, and the apple of eden doesn't kill cowering men. The second time, I killed all of the guards but one, who was alive but wracked in pain on the ground. The third time I killed all of the guards and the game didn't register that they were dead. This is a simple matter that can be fixed by going to the Xbox dashboard and playing the game again, or turning off your console because it's overheated. Oh, and this isn't a spoiler because it says in the achievements 'Obtain the Apple of Eden'
Review so far: an alright game, though would be a buy for those who have a Live account so you can play some multiplayer to ebb away at your frustration.
