Might as well join in the fun...(btw, this is my first post, just been approved a few days ago)
Even though I bought it last year, I finally started up the PC version a few weeks ago, thinking I should finally see what all the fuss is about. I just got to Arcadia.
And damn, this game is dense. In the good way. The level of detail, the art direction, the sound design, all the creepy things splicers mutter to themselves, the simultaneously cheery yet ominous nature of all the plasmid training videos...they did a pretty good job making Rapture a pretty uncomfortable place to be in. It's not exactly survival horror, but it's pretty close.
In fact (and this is just my personal reaction), I sometimes feel like it's too detailed. This sort of goes to a problem I'm having in general with this generation of games, but I find that when a world is this detailed and has so many different moving parts--water rippling, sparks flying, lights flashing, steam hissing, walls creaking, and all the other little things they put in to make the world detailed and interesting--I find it difficult to "lose myself" in it, and feel kind of overwhelmed. and distracted by everything. It gets worse in some battles, if three splicers are all taunting at once, plus all the other sound effects going on, I find it difficult to formulate a plan of attack. Again, that's probably somewhat intentional--Rapture is not supposed to be a pleasant place to relax (at least, not anymore). But the more detailed and high-res game environments get, I feel like this sensory overload might get worse with me. Oh well.
I'm still digging the hell out of the story (and I've thankfully avoided all spoilers as to what lies ahead). I genuinely want to find out what actually happened to this twisted hellhole. Not many game locales do that for me.
