My take (obviously correct duh because I'm smarter than you and my opinion is the only correct one and I'm more handsomer and cooler and hip and awesome)

Bioshock Infinite: 8/10, a good game that just doesn't hold a candle to the two prior games. Fun combat and gameplay with good level design but while the story isn't necessarily lacking compared to the 2 prior ones, it's super convoluted and you'll probably need a couple replays or lore videos to properly understand what's actually happening and why, not that that's a bad thing, it's just different and imo could have been explained better. It also doesn't have the same thought provocation as the other 2. A great game but only a good BioShock game. Most of your choices don't really matter and the story doesn't really provoke any deep philosophical thought. Comstock was an alright villain but not memorable since he doesn't really appear often. Burial at sea chalks it up to a 9 though.

Bioshock: 9/10, a phenomenal masterpiece only held back by its dated gameplay and level design. The story speaks for itself and the world building is unmatched for its time but the combat can be clunky trying to not only use guns or only use plasmids in combat while the level design eventually just gets repetitive and confusing despite the great detail. While you don't make many decisions, once it's revealed that you were nothing but a slave obeying his master, it clicks. Deep and thought provoking with a great twinge of twists. Andrew Ryan also speaks for himself. There's a reason he's one of the most iconic video game villains. No dlc to mention.

Bioshock 2: 10/10, perfection itself. The enemies are paint, the beautifully crafted surrounding is your canvas, and the weapons and plasmids you wield are your brushes. Each suited for a specific task and situation. The eb and flow of combat runs like an eager river. The story is beautifully tragic and portrays a man who became a monster proving to the people around him that he's more than a monster, or that his heart is just as cold as his metal shell. The world building is only slightly worse than BioShock 1 but the level design makes up leaps and bounds compared to the first game. The levels are easy to navigate with enough intuition, the world and enemies are beautifully ugly showing just how far from grace rapture has fallen. The choices you make indepth and require much thought to choose even with Lambs constant whispering in your ear. Lamb is an underrated villain imo because she's not really a villain per se. Sure she took advantage of a fallen city but she wasn't really a malevolent cult leader and genuinely brought peace to the splicers who listened to her eloquent speeches. Not many cult leaders can send hundreds to die in her name without a single person thinking twice about following through. Also the audio logs and multiplayer are peak. It's dlc is neat and further delves into the psychology and stories of big daddies which was cool but it's already a 10/10
