Mass Effect 2 and 3: ME1 is one of my favorite games of all time. I'll never forget the first time playing through it, learning about all the history and back story the game had. First time seeing the Citadel was a magical experience. The whole game just oozed with an incredible atmosphere that I feel isn't really present in ME2 and 3. It also had a cohesive and well paced main story that always felt like you were doing something relevant. ME2 and 3 just didn't give me that magical experience. I've replayed ME1 many times, even recently, and it still holds up to me. ME2's irrelevant plot to the Reapers, 'streamlined' RPG features and global cooldown system really hindered my experience with ME2. It wasn't a bad game, but it was a sign of things to come for ME3, which for the most part is pretty awful with a few moments standing out as being decent. (Rannoch and Tuchanka). The quality of writing just took a nosedive here though.
Dragon Age 2: Again, I consider DA:O to be one of my favorite games of all time. (Up there with Deus Ex, BG2). Dragon Age 2 was probably the most excited I have been for a game in a very long time. What a let down. Horrid writing quality for the most part, extremely boring environments, frustrating gameplay mechanics (wave combat, night time enemies respawning, reused environments, bad paraphrasing, etc) streamlined combat abilities (little to no supportive/cleric stuff compared to Origins), and a main character/family with motivations I just could not get into or care for.
Hitman: Absolution: Sigh. Why oh why... Blood Money was borderline perfect. Incredible level design and an amazing and atmospheric soundtrack crafted some of the finest sandbox gaming moments ever. All of this gone from 99% of Absolution. Kyd's score is greatly missed. Instinct was a bad inclusion in my opinion, and for people who wanted Absolution to play like Blood Money by playing on anything above Normal (which starts to gimp Instinct features iirc) are given in a return one of the most artificially difficult and frustrating games ever. The game revolves around instinct and playing on anything that gimps it for the most part makes it at some points borderline sadistic to play. There are glimpses of a good game here, the gun play and movement mechanics are solid, and in the few missions that are sandbox the game does start to feel like a Hitman game. But even then, it's not perfect as the ways to complete your contracts are severely limited and uninteresting. The constant point A to point B missions and extremely frustrating instinct and disguise system made it a chore for me to get through this game.
Max Payne 3: It's a shame. The game plays so damn well and looks great. But it doesn't feel like a Max Payne game. Lacked the atmosphere of the other games and the story was pretty uninteresting.
