Edit: Okay, I guess some clarification is in order, based on responses:
1. The TableTop rules do not allow targeting of specific body parts durng normal combat.
"What About Targeting Computers?"
Targeting Computers are Clan Tech and will not be available to Inner Sphere until until the 3060's, so the targeting of specific body parts in the Inner Sphere would be non-canon in 3049. The Devs would have to break canon and introduce Clan Tech prior to introducing the Clans, themselves. (they'll hit the edge of the Periphery by Game Lanuch in summer, but good luck getting their equipment before they reach the Inner Sphere...)
2. RPGs use "virtual dice" or random-number-generators to determine the effectiveness of combat manuvers; Simulators typically do not. If you want a Sim environment, then a perfectly aimed shot will never miss, if you want an RPG environment, then your shots will have a chance of hitting as long as you're locked onto your target regardless of your actual aiming skill, and your chances of hitting a target will change based on your XPerience and how that XP affects the modifier function that acts upon the value generated by the virtual dice. (by "perfectly aimed" I mean a stationary shooter firing at a stationary target with a target lock well within the weapon's effective range)
Additional Edit: You can't "aim at a body part" without a Targeting Computer accourding to TableTop rules, which the Devs say they will try to follow as closely as possible...
THEREFORE
The Devs have to make a choice:
1.) They can allow targeting of specific body parts without a Targeting Computer, which will break canon, but they are allowed to break canon here-and-there for gameplay purposes.
2.) They will give us all Targeting Computers, which, for 3049, is a violation of canon, but they are allowed to break canon here-and-there for gameplay purposes.
3.) They will not allow us to target specific body parts without a Targeting Computer, but Targeting Computers will be available as an optional equipment/modules... which, for 3049, is a violation of canon, but they are allowed to break canon here-and-there for gameplay purposes.
4.) They will not allow us to target specific bodyparts, meaning no Targeting Computers; your shots will automatically disperse themselves across the target you are currently locked-onto using a random-number-generator to simulate the effects of dice rolls. Firing without a target-lock means your shots will go somewhere randomly in front of you but not exactly where your reticule is pointed because firing accurately at where your reticule is pointing requires a Targeting Computer (which is unavailable).
Options 1 and 2 will support a Simulator-like environment because your direct actions dictate the results. Option 4 supports a RPG-environment where chance and accumulated XPerience overrules your hand-eye-coordination. Option 3 is a mix, obviously.
