This probably is the perfect game. If you played Bioshock, this is essentially the same style game, only in the clouds, not under the waves. Vending machines, weapons and Vigors (Bioshock=Plasmids.) Looking inside almost everything for food, drinks, etc., same interaction, etc. The city, it's back-story, history and major players are somehow familiar. It's the robber barons of the 1900's without any control. It's intensionally racist, echoing the attitudes of the era. For example, in one area bathrooms are segregated - "Blacks and Irish" use one (and man is it disgusting) and the upper crust whites the other. There's the battle for equality, and our alternate dimension hopping heroine trying to fix things. This alternate dimension aspect is totally cool. Eventually you can see the "tears" in reality and can have Elizabeth open alternating tears to aid you in battle. You'll have access to weapons, barricades, medical supplies, skyhooks and more. Plus she's a great companion - miss something, like a lock pick or locked door? She'll point it out. She'll also toss you ammo and supplies during battle.There are tons of weapons, and all can be upgraded with vending machines. You'll also be able to upgrade shields, health and salts - you'll find these shifting potions - each can be used to increase your shields, health and salts one level at a time. You pick which one the increase goes towards. I put 75% towards health and the rest towards the others, until health was maxed. Shields recharge and salts are plentiful - you almost never run out of salts (the power behind your powers.)There are a few side quests - do them! The rewards are great.My favorite weapon is the hand cannon - basically a 44 magnum revolver. The 2nd weapon alternates with the battle. Sniper rifle, carbine, heat gun, crank gun (Gatling gun), pistol, machine gun, sawed off shotgun, shotgun and more.If you die in battle, you're penalized dollars and revived with partial health - same as in Bioshock. If you walk off a ledge or bull a stupid move (like hop off a balcony) you're not penalized. There are many places I just had to try this. Occasionally I wound up on a balcony and once found a side quest. The navigation system is cool. Get lost? Where's my goal? Tap the appropriate control and and arrow points the way.Training is also unique. You play games at a carnival to learn the weapon and power basics, and can win money.2nd play through: Mastered the skylines and freight hooks, kept hopping on for all my kills (when possible) - the strikes and kills from skylines are deadly, especially with the right clothes. See the bottom for more - with spoilers for 1st time through - 2nd playthrough comments. Lets just say the plot really - REALLY - has a lot of "no effing way!" moments! But it's not a "Game plus" - your character has no bonuses and everything except accomplishments and partial accomplishments are lost. For example, if you were half way to an accomplishment at the end of the previous game, that's still there. But your weapons, vigors - etc. - all back to the beginning.My only gripe is that there is a first day DLC - it costs $20 for the DLC. You get more weapons, power upgrades and locations. Yes, it's worth it. But this really should have been included in the game. But they have to pay for a $100 million development cost somehow....I did experience a FEW glitches. Missing bodies in one scene, but I still had the "search corpse" option. Frame rate crawl in some action scenes - I installed the game, it's not running from disc.They really went with the whole multiverse thing to the extreme. The ending? Wow. Mind blowing - several huge reveals. 1-2-3 punches to the hind-brain. Plus a really funny comment by Booker about one reality Elizabeth takes him to. Will there be a part two? We can hope....Spoiler alert:.......On my 2nd play through I paid special attention to the recordings and the conversations between the brother and sister. There were so many hints dropped! Plus we'll figure out that our poor Pinkreton is nowhere close to his home dimension. We see a shift when he's looking at a statue - the 1st time through I thought it was a poorly done ribbon blowing - nope. Then when he's watching Comstock lecture him from the floating blimp TV screen - and all the soldiers are kneeling down - he shifts dimensions - the nose bleed and sudden change in the way the screen appears. So Comstock can control tears - that's what the siphon was for. He shifted dimensions at will. There's more - play again. I did the 2nd playthrough on "hard." I'll play a 3rd time on 1999 mode.
