Is it worth the 1.4 gigs of space its going to take up?
Depends on how valuable 1.4 gb is to you. It's an awesome story so far and really good characters and dialogue. Some of the character interactions (i.e. banter) in the game is hilarious. However it is very early on in it's development. So much so that there isn't even one full sex scene yet. You be the judge of if that sounds worth it.
