You actually dont "change" the plot.Its more complicated than that, but you know what I mean.

Just to clarify to snowprince, there is only one actual true ending, like Danganronpa.But it will be spoilers if I say more than this.

Believe me, its better than Danganronpa(Its the same developer also).The premise is basically the same:You are locked in a place(a ship in the first game and a base in the second) and you need to escape.But the way it is told is simply brilliant.It is more of a book than Danganronpa is, but it makes for a better game in my opinion.If you loved Danganronpa, this is a must buy.But start from the first game, or at the very least the second one, since the third one will be heavily tied to the previous games on the franchise.

I think it's a lot better than Danganronpa, because in Zero Escape you can actually make decisions and change the entire plot.

The first game had 7 endings and a lot of different paths. I don't even rememeber if I saw everything possible...

Thank you so much you made me really eager to try the second one. I do not own a DS anymore to play 999 (will do if the vita/steam port if confirmed) but I'll jump on the next VLR game i find !
