Personally, I think they made a few too many sacrifices simply to run with the control scheme they wanted; Parrying being one of those and another being that magic can't comfortably be used along two-handed weapons or Sword+Shield combinations. So if one wanted to play a Paladin type character that uses restoration magic alongside his Mace and Shield, he'd have to keep switching around his equipment to do so. To me, having to do so feels like a work-around rather than a carefully designed system. Bow users will too have to faff about to use magic, and worst of all are the dual-wielders - who can neither block nor cast magic comfortably.
I suspect it'll cause a natural division between martial based characters and magical based characters, akin to Morrowind, where characters are less likely to unintentionally delve down the paths of magic. Comparatively, in Oblivion characters tended to inadvertently push their Restoration skill pretty high, since magic regenerated naturally, you had a readily available healing spell and you could always have it equipped. This made many characters become dual-classed or Jacks-of-all-Trades without players really incorporating that into their plan. Now, while I'm sure there'll be people who like that, I'm personally a bit divided in opinion, because I like playing Jacks-of-all-Trades such as Bards or simple Adventurer type characters. Oddly enough, they (Todd, I believe) have stated in the trailers that they wanted to step away from making players "Choose" what they wanted to be at the start of the game, but have the player instead grow into the classes they want to play. The effects of "Two Hands System" I suspect will be completely contradictory to that, coaxing people into set roles or "Classes" because it's far more comfortable using the system that way.
For me it'll no doubt cause a bad case of
Altitis (The mental disorder in which you make too many alternative characters
) because I will be unable to comfortably incorporate all the elements of the characters I like to play in just one. Not due to the restrictions of the skill system, but due to the limitations of the control system. I
was pleased to see that Dragon Shouts don't occupy any hand slot at least. It should spice up the gameplay for Dual-Wielding characters. Amusingly, the only conceivable reason they would set up this system is to allow Dual-Wielding to begin with, and they probably get the worst deal of the bunch. :shrug:
