I thought Infinite was one of my favorite games until the ending twist. You are the antagonist from another dimension, the city is suspended because of some quantum thingy particle, and Columbia never existed in the first place because you were supposedly killed in the past by three simultaneous different dimensions of Elizabeth. Loved that game until the last half hour absolutely trashed my opinion on it.
Episode 1 was okay. Return to Rapture, return of some of Bioshock 1 & 2's old gameplay, exclusion of the insanity that is Elizabeth's tears. Elizabeth still uses her tears, but it's for small plot elements and corner cutters, which is how they should have been in Infinite's main story before they brought in the cross dimensional insanity. It was wonderful to see Rapture alive and lackadaisical like what Infinite showed us of Columbia, it was great to have Booker and Elizabeth back and communicating with each other. But, the DLC was short short short: Took me about three hours my first time through, and we got a small slice with only a few choice enemies, one returning Plasmid, and one new gun. It was hard because of the new weapon implementations, but it played so similarly to Infinite that it wasn't holding my interest. Which isn't bad, because I liked Infinite's combat. Bullshit ending, it's really boring the DLC saw so little Skyhook usage.
Episode 2 was an absolute treasure. Much longer, played so differently to Infinite and Episode 1, the story was pretty brutal at the end, and the focus on exploring worlds is back. It was great to let Booker take the support role, it was a great move by Irrational to have Elizabeth be slower and worse at gunplay in comparison. Stealth, while fresh and new, was ultimately pretty dang bullshit and easily exploitable, especially later when you get the plasmid modifiers. But that ending, that last hour or so after Ryan's cameo could not have been done better. Experiencing Elizabeth's torture, saving the Big Daddy, witnessing Suchong's murder, and the reveal of the Ace in the Hole are going to stick with me better than anything else in Infinite. I would've been happy to buy this part as a $30 inclusion, I'd take this as an appropriate prequel to Bioshock 1 anyday.
Okay, but:
Episode 2's return to Columbia and Daisy Fitzroy was unnecessary. Trying to justify Daisy Fitzroy as being anything but a poorly written character is going to fail, even if you try incorporating the Luteces into it. Going through Columbia when you're not fast-paced, Skyhook-riding Booker is boring when you're back to crouching everywhere and meleeing oblivious AI.
The game continued to rip out more of the RPG elements, even after Infinite's paltry RPG elements. Weapon and Plasmid upgrades are sparse or just not there, Infusions and clothing modifiers were removed entirely from Episode 2, which means money in that game is worthless because there's nothing worth spending it on.
The Big Daddy fight was nostalgic, but he was easily dispatched because of Elizabeth's tears and the fact that he couldn't touch Booker when you use a Skyhook. Handymen are a lot more formidable, because they shock Booker if he uses a Skyhook to get away, and because they can't be completely stunlocked without any effort on your part. I wanted to face off against a Big Daddy properly, without easy getaways and a much better arena to use, but it of course never happens.
The entire section, especially Episode 1, needed more new tools and fun things for Booker to do to compensate for the lack of... everything. Plasmids, weapons, Skyhooks, alternative enemies, Elizabeth's interactions, and length. If we saw the return of the Chemical Thrower or alternative ammo types, please should've returned.
