Is this game worth trying yet? or is it better to experience it through videos and screenshots?
That's almost impossible to answer, the game is huge, its unique, its beautiful.
Its also complex, there is very little in the way of hand holding so the learning curve is very steep and you will find it frustrating, its also riddled with bugs, which you will find equally frustrating, but if you can bear it, if you have a high tolerance for it and a lot of patience it can be very rewarding.
The developers are trying to do something that no one else would dare due to cost and complexity, they don't have the backing of a wealthy publisher, what they have for funding is us, so the game must be open and playable as its being developed, the result of that is its a very unfinished and unpolished game.
I think what i would say is this, if you don't mind all of that and want to experience it through its development, sure, go for it, but even that is subjective, you may just not like it full stop, if what you're looking for is a polished game then steer well clear of this, you have to have a high tolerance for it frankly being broken at times and its a good thing be quite nerdy.
