Elgi, I personnaly do not get why some of us here connect a more challenging combat system with real life agility? There is no more agility required for such a combat than for pressing the right button for a spell or a potion like it's done in so many RPG's.
I've always tought of myself I wasn't the best gamer, I was really bad at FPS and Action games. I tought it was because I hadn't sufficient coordination or agility, but nothing was less true, I just didn't think. The handling of a game is something you grow customed to quite easy, mastering that is a question of mind. Offcourse games like Quake take more than just thinking, it takes reflexes, real hand eye coordination but those are competive fps games, this is a singleplayer RPG we are talking about.
