I picked up Bioshock 2 in the recent Steam Summer sale and have been putting a little bit of time into it here and there. I'm coming to this game pretty freshly off of finishing up with the original Bioshock, which I only played for the first time about six months ago. I adored the first game for its atmosphere and storytelling; even if it wasn't the best shooter mechanically speaking, running around Rapture and learning about what had happened and just seeing the sights was an amazing experience that I was really eager to revisit. 
 
And atmospherically it's great. I have no real complaints about the timeline and the larger NPC characters and their relation to the original game because if I can suspend my disbelief enough to swallow a city under the sea destroyed by politics and genetic manipulation I can handle just about anything... Rapture is great. 2K could sell me comics and direct to video movies and shitty licensed novels written by Kevin J. Anderson and I would probably eat them up. I am part of the problem. 
 
But damn, is this game harder or what? I'm supposed to be a Big Daddy, but I feel amazingly fragile prior to my upgrades, and unfortunately the route to upgrades is engaging in combat with Big Daddies and splicers.  Which incidentally leads into me feeling that resources are even more scarce in this game than the previous one. Survival horror scarce... and I'm still kind of chewing on whether that's good or bad. In Bioshock, the choice to harvest or free a little sister really came down to pressing one button to be nice and get some stuff later, or pressing another to benefit right away. I never harvested a single sister in the first game, and while I haven't done so yet in Bioshock 2, I am feeling sorely tempted to just harvest her and save myself the resource drain of getting into the extra combats -- I have enough to worry about with Big Daddies, wandering Splicers and the Big Sister. I assume this is what they intended, but I'm not sure how I feel about it just yet. 
 
Thoughts?

I agree in that you're surprisingly underpowered as a Big Daddy but I never found it much harder than the original, myself. Once you get more of your upgrades and plasmids, though, you will become the meat processing Tank that you'd want to be as a Big Daddy ;)

I very rarely let the sister gather ADAM. I just killed her big daddy then took her to the hole in the wall. 

I thought this thread was about a Link to the Past :(

well a you are the first big Daddy(Delta series) you are not like he ones from the first game. the extra adam will come in hany for th e late parts of the game.

I'm also extremely LTTP with this. I've been a BioShock fanboy since the first game came out in 2007, but let the internet sway my opinion and never played this 'till now. I'm enjoying it, though. I'm too in love with Rapture and the overall fiction of the franchise to let any narrative shortcomings ruin it for me.
 
But I do agree that resources seem to be more scarce here when compared to first game. I enjoyed playing through BioShock on hard, and jumped right into this one on the same difficulty, but I'm almost regretting the decision.

While I will agree that as a Big Daddy you are kind of weak, I won't agree on you that the game is hard. It's just different from BioShock now, and you ave to play it differently. Rember the melee-button!  
 
And what does "LTTP" stand for? 

"And what does "LTTP" stand for?  "

Ah, thanks! 
 
I loved the melee-button, and the game would still be better even if it wasn't dual wielding (wich of course made it even better). I am one of those who loved the game because it didn't try to be BioShock but rather it's own game.

" @HellBrendy: Was I the only one who read that as "Some "Link to the Past" thoughts.... "? "

Oh, so that's the meaning... Well, it's still "[something] to the [other something]" :P
