Despite a rocky start, the game had potential. Bug fixes were coming out, new features were being added, and the game was finally starting to live up to what was promised.
Until the corporate overlords at Take-Two Interactive decided to shut down Intercept Games and effectively cancelling development, taking everyone's money and running, and leaving the game an unfinished mess that doesn't even come close to the original game in either content or quality.
Don't buy this game, get KSP 1 instead.
