There's another demographic that likes easy gameplay, heavy on the atmosphere: aging gamers. I'm coming up on 40, and I no longer have the twitch reflexes to play some games on Medium, let alone Hard. (Having to step down to the easy difficulty on both Kingdom Hearts II and Viewtiful Joe was rather humbling; I still think the difficulty progression for the latter, Kids-Normal-Adults, should be reversed.)
I'm old enough to have played, beaten, and loved the floppy version of the first System Shock. (Don't think I ever finished the CD, though.) I gave SS2 a miss because, at the time, it was actually too creepy for me. Not having that problem yet with Bioshock, surprisingly enough; either the added years or the lack of worms must have helped. My lack of experience with SS2 probably makes this game seem less unoriginal, too. Good.
I accidentally spoiled myself about certain key plot elements, so at this point I'm just seeing how it all plays out. This isn't much different from how I'm used to playing classic Sierra/LucasArts adventures, with a walkthrough in my lap: as a multimedia experience, not a puzzle. So far, I haven't died once, but it's still early in the game, and I picked Easy difficulty despite having played shooters before, since I didn't know how punishing (or lenient) Bioshock would be until I actually got into it.
Yes, there are Vita-Chambers about every 20 yards; one wonders how anyone ever dies in Rapture. And yet, I point out to some of the complainers that all these really do is automate the quicksave/quickload process that so many shooter-players have become so habituated to that it's practically a reflex action. If the "serious" players are going to use the save/load feature to almost completely eliminate risk or waste of resources, why not put everyone on the same footing? I realize this leaves you with nothing for your twitchy trained fingers to do, but I can't really say I'm sorry. The only thing I might change is to make only one per level, so you have to jog farther and there are more opportunities for what the old Hacker's Guide to Sin refers to as "post-mortem confusion, which sometimes becomes pre-mortem confusion."
I don't like the lack of inventory and the use-it-or-lose-it health pickups. And yet, I note that both DOOM and Half Life (1), giants of the PC shooter genre, had the same system. So ***** if you like, but don't say it's a console thing.
Just a voice from the far end of the pool: not a console gamer who thinks that the FPS genre begins and ends with Halo, or a dilettante used to Minesweeper and Solitare, but a former serious PC gamer who just can't keep up anymore, and is glad he doesn't have to play with two fingers on the F5 and F8 keys.
