A story based in the player's decisions with more than 50 endings including 'bad end', 'fatal end' 'true end' and many more. The game has mostly 3 heroines, but is at least possible to get a route (at least 1) with any girl that appears.
R Academy doesn't have consistent story, as it changes with every decision, whether is immediate or at the end of the game. Basically an experience in acts.
