Simply one of the best games ever produced.
Not much to say about it without writing for an hour, massive RPG, with in depth decision making, dialogue options, and character creation (Although the customization is lacking a bit).
Seriously, this is a game everyone should play at least once in their lives, despite the amount of information and menus it has, it's somehow pretty self explanatory and intuitive. But of course, it's still an overwhelming experience for first players and is not recommended for people who haven't played many games.
Once again, please make yourself a favor and play this game, it's worth it.
