Once in the game, the first thing I noticed was a marked improvement in the localization, specifically the dialogue. This alone is such a huge improvement that a game I once had some serious doubts about now seems a whole lot more viable. Gone are the completely non sequitur bits of conversation and skill explanations that were so distracting in the beta. Moreover, whoever did the rewrites was deft enough to clarify the copy without losing the flavor of the original. Well done.
From everything I've seen so far however, no matter what you choose, the starting area quests and abilities are all pretty much identical.
While the change in character from beta to live gave me a chance to try out a different storyline and gender, as with the beta, there is only one character slot available. This seems to be a policy with Snail Games, and not a freebie vs. paid account issue. I personally disagree with this policy, as it allows little margin for error when creating a character, and forces deletion and re-roll in order to explore different avenues of game-play.
