I do that to...quite a lot actually. No matter how awesome one character turns out to be, or how brutally thrilling the given style's finishing moves are, I always want something new.
And, the fun part is, goin through all those quests, forests and areas again and again never gets old, because it's somehow different. The only other games I could replay this much were Gothic 1 and 2. Something about forests, sundowns and sword play reminds me of an autumn stroll in my childhood...something clicks with me with these games...but gettin off topic here.
