This board is too full of gushing and b_tching about current games. It's time to add some more of the the PGC forums' traditional baseless speculation and wishful thinking.
The Subject: Too Human - gameplay mechanics, desired upgrades, features, etc. are all fair game.
The Rules: Posts containing facts are not permitted, unless those facts are couched between sound speculation.

Posts containing nothing but the obvious are a waste of everyone's time, don't do it.
I'll start the ball rolling:
minor upgrades:
Muscle type - contol the balance of fast and slow twitch muscle tissue. Quick customization of speed and strength versus stamina with little impact on your humanity.
Adjust where tendons connect to bones: moving them out increases strength and speed (better leverage) while reducing range of motion.
Braces - you gotta look good while your kicking butt!
Eye inversion - human nerve cells actually go over the top of rods and cones, requiring the use of axons without myelin sheaths (slower conduction speed) and reducing light sensitivity. Squid have eyes that are built right, so I imagine this shouldn't be too difficult (may even be genetically engineered in to the general population by then).
vitamin C production - not actually an upgrade, but something I'd like to see mention of in the game is fixing the genetic defect only present in humans and chimps that makes it so we cannot produce vitamin C on our own.
Medium upgrades:
catalyst based power plant - Permits cyborg parts to be run off of food taken from the digestive system instead of a battery (yes, I want the guy to have to eat and recharge to power whatever he does to himself - everything comes at a price).
scent control - in case you need to sneek past dogs, or go out on a hot date.
stereo sense of smell - snakes actually do this, they can "smell in 3-D," that's what' their forked tongue is for. May be possible just by splitting the nasal cavity.
Active and Passive sonar - speaks for itself, I want the guy to be able to "visualize" his surroundings with sound. Useful for detecting false walls, cybernetic implants (sensitive to the density of the material sonar is being used on), seeing though dust too thick for infrared, etc.
Increased speed (mental and physical) - Upping your mental speed slows the game down. Increasing your physical speed speeds you up. You'll need both to be really effective. (novelty = distinguishing the two) It will be interesting if SK doesn't "speed up" gravity like so many other visions of super speed do (when Neo tried to fall back to dodge the bullets in The Matrix, he would have lifted his feet off the ground instead of falling back because gravity is not strong enough to pull him down that fast).
Vocal control - permits impersonation, ventriloquism, etc.
Advanced Upgrades:
Continuous feed lungs - by having an extra air sack, it's possible to keep fresh air moving over the lungs, even while exhaling. Birds do this.
Continuous feed heart - an eight chambered heart (aritficial or not) can keep blood moving constantly, instead of a pulse.
Poison cells - for the close in and silent killer, have consciously controlled poison cells similar to those found on a jellyfish.
Interface needle - Hack in to a guard's brain to gain access to sensitive areas without going in yourself, pray no one sees the needle mark, though.
Yes, I want this game to be that detailed. The game is also supposed to contain a library where you can read histroy from now to then. I want to expand that. I want the game to be three discs - two for the game/FMVs, one for all the text! Hell, don't waste space on the FMVs, fill that up with text, too! Maybe they should just make this game a MUD...
