I've played some more. It looks like this one can turn out to be the best RPG I've played in years. I'm liking it very much so far.
I like how elements are dropped here and there, so you learn little by little. It's not like you have to read a thousand things before you play. However, it's important you grasp all the concepts. Alchemy is very interesting, if a bit slow. When picking up herbs, it should work like Oblivion: you press the button, you pick the herb, no need to enter a submenu and double click on the herb. For remains it's almost the same, you kill something and you have to wait two or three seconds for the body to be collectable. It's a bit annoying.
Freedom of choice is good, although there seems to be the only freedom you've got. Story is a bit linear, although, from what it's said in the game, events can be quite different depending on your previous choices. That's great, although probably a second play through would really show how different this events may be.
I think it's a very streamlined RPG experience. Streamlined in a good sense. There's not many stupid secondary missions, just some collect this or that (which usually are tutorial missions) and you feel compelled to continue. To put it short, the next goal is always at hand, which is fine for me.
That said, I'd like a bit more open areas, I feel constrained when walking roads and seeing fences right and left. Besides, is it always cloudy in the game? Will always rain? I like me some blue skies from time to time :-/
