(1) There is a timer for quest ?
I haven't encountered any quest timers as such, but there's an in-game clock. Everything you do advances the clock so there's only a finite amount of shit you can get done during a day. So for example if you haven't figured out how to put together next night's rent during the day, you have a Problem.
(2) Can you fail to build your character, to the point of being stuck ?
Maybe? It's partly luck though, if you make a really shitty build you might still succeed in a lucky die roll. I couldn't tell you just how likely it is for you to fuck up the game just by build choice. IME getting completely stuck (or getting a Game Over condition) does require a combination of bad build + bad decisions. I'm pretty sure it's possible to get into a situation where the Thread of Prophecy is Severed etc.
And third question: Have you ever been surprised by the outcome by choosing an answer, or can you make an unambiguous choice?
Haha all the time baby! Not just the dramatic ones either. It feels very fair though -- it's only occasionally that
you do or say something surprising, it's that people don't react to it like you might expect, there's something you missed, and so on.
Prime Junta Would you say it lives up to the hype, a revolutionary rpg etc etc?
I would say so obviously but then I am a self-confessed fanboy. This is pretty much my dream storyfag RPG. Whether it gets enough traction to be genuinely revolutionary is a different matter.
I've alluded to this before but I'll lay it out in a bit more detail here. The thing is that this combination of RPG and adventure game mechanics is unusual and I think many or most RPG fans expect more
game in the game: specifically, game as in tactical combat. This
is very much "talking to people, the game." There is a tactical aspect to it -- specifically: you need to be tactical about spending your skill points for re-rolling white checks you really don't want to fail (and might still fail, due to sheer bad luck), but at the very least you need to adjust your expectations of what a cRPG is to get past that. And if the main reason you play RPGs is to build and test your skill against the systems and the world, then this probably isn't the game for you.
Btw with a cheat characters with maxed stats would break the game removing all choices since you can do all?
If you maxed your stats with a cheat you would have a
very chatty game. All your skills would be continuously haranguing you, pointing shit out to you, and generally just swamping you with stuff. You would also succeed in most of your die rolls and miss out the fail states.
However you would still have a
ton of choice in how to play the game: you'd still be deciding which option to pick in a dialogue, building up your personality, and coming up with Thoughts to develop in the THC. There are the Copotypes and the politics that Marat Sar alluded to. So even with a cheat you would have to play through the game several times to experience all of it.
