I honestly hated this game when I first started playing it - but wow am I glad I ever stuck it through the grind to push through.
If you're looking for a fast payoff this game may or may not be for you. This game is as much about training your students and staff as it is yourself. That being said when you finally get over the initial hike and start unlocking scenes wowee - prepare to bust nuts.
Interesting mechanics, a good variety of characters, and unconventional teaching methods that deliver results in a purely fantasy world leading to an incredibly hot adventure. An alternate reality where as a headmaster of a unruly school (soon to be disciplined by you wink wink nudge nudge) you work to improve the discipline and education of your students while simultaneously working to gain more power by proving your methods work - & thereby gaining even more prestige and willingness from your coworkers and students to do dirty, dirty things.
Nice.
