At 6 yrs old I played through the Fighting Fantasy Gamebook "The Shamutanti Hills" ... and ever since, almost every character I make is something akin to the Fighting Fantasy generic 'Adventurer': light armour, blades, sneak, security, destruction, restoration.
Game looks fantastic; but it'll be the ease of mod creation and application that'll make or break it for me. Like Oblivion or Fallout 3/NV - if the community (and myself!) can pump out some spectacular mods then are we in for a game of the decade contender?
