X-Change has been referred as a visual novel rather then a game. You get to make choices that affect the ending like Fallout or Mass Effect.
So you're a collage school boy the turns into a female. You get to pick what your dialog is going to be and what you do in the game. This will affect what endings you get and if you remain a woman or turn back into a man.
Also, I think you may need to know this, what we have here is a porn game... or visual novel porn thing. Whatever. So your enjoyment really depends on what you're into. I was honestly really bothered by on part of the game where you're raped on a bus. Well if you're into the type of stuff I guess you got something to look forward to.
This game has humor and I guess it is what it is. I enjoyed some parts of this game.
