I played through Event[0] and I didn't like it too much. The basic idea of the game is that you're the last astronaut on a space station and you're trying to get back to Earth. You do that by communicating with the AI that oversees the station and performing tasks/solving puzzles to open locked doors to progress.
The space station is pretty small (only about 10 rooms) so there isn't much exploration in the game. The core gameplay mechanic is communicating with the AI which is done by typing out questions or comments at various computer terminals. It's sort of like those adventure games from the 90s (like Hugo's House of Horrors) where you have to enter the correct text to move the story forward. All of the depth in the game is locked behind this communication system (which apparently lets the AI generate 2 million responses according to Wikipedia). Also, the ending can change depending on your demeanor towards the AI (whether you were friendly or antagonistic etc.). Of course, you won't actually know that there are alternate endings unless you go and look up the achievements or something.
The problem is that none of this depth will really be apparent to the player. All the information required to actually progress the game is given to player in a very obvious way but all the backstory and context needs to be gleaned from the environment. If you don't ask the AI about certain things you will never get to know the (alternate) history that the game is set in. Also, a lot of the story is delivered through mundane log files which are tiresome to read because they also have a very low signal to noise ratio. At the end of it all, the entire game is about typing questions to the AI and getting responses to progress. If you don't ask enough questions or the right questions you'll be left with a very vague understanding of what happened on the space station.
The general beats of the story itself are sort of predictable as well. When you think lone survivor on a space station talking to an AI, what kind of story do you imagine? Yep, this game is exactly that.
It's not a bad game as such. It was a student project that they decided to expand and release commercially. I just didn't like it all that much.
