This game will probably go down as one of the best open world RPGs of all time. It did get me thinking though about RPGs and characters that can be many things (some BioWare RPGs now) versus character specific RPGs that let the player develop the characters from a point but they have a prior background (the Witcher games). I think there's one RPG that mixed the two perfectly, and that was Knights of the Old Republic, but in most instances it seems like writing RPGs is much easier focusing on an established character than an RPG that gives the player full control over many aspects of a character. To put it bluntly, I think I've come to prefer RPGs like Witcher where there's a pre-established character such as Geralt over RPGs that give you someone like The Champion in Dragon Age 2 where the writing can't be as specific.
Anyhow, the only major disappointment is that it feels like there was a missed opportunity of a unique multiplayer online experience with this game, and that is purely with Gwent. It would have been perfect. It's funny because I usually don't want multiplayer even thought about for RPGs like this, but that game lends itself perfectly to something like that.
