When I was still in college I played Fate Stay Night and other novels in class (and the professor saw Saber's H-scene, good times) and passed games for thesis, now I'm done and have nothing to do, so tell me what should I do now?
A 2D Dishonored like game (in the style of Castlevania) in a complete open world in which you are a former Assassin working for the Church who betrays you and you plot your revenge, take your pick: a path of blood? a path of shadows? a path of lust? Whose Lilim will you grant the land? Are you willing to face the consequences of your actions? No objectives, no missions, just choices. How will you enact your revenge? To kill everyone you see? To manipulate the market and make them sell aphrodisiacs? To transform the leading women of the city into mamono to make the city fall? The choice is yours.
^ This game, by the way, was one of my drafts that I passed, AND WAS ACCEPTED (LOL) But I didn't go through the project because I don't have the guts to show it to the panel (what the fuck did I get drunk on when I sent the Draft, I need it again. I need another dose of courage. XD)
Or an X-Com game? set in the Future, Humanity has perfected a Utopia (Grey Goo) and got their shit together after 3 World Wars, however, spacequakes occur, taking hundreds of thousands of the populace with them and nobody knows why? You are made commander of the exploration division, your job: Investigate these phenomenon, make contact, and if things get worse, annihilate the threat.
Or a 4X game wherein Earth is destroyed and you are forced to crash into the world of Mamono. Decide the fate of the Colony. Harmony, Purity, or Supremacy? Science or Magic? Make the necessary choices to ensure your survival. (should I go Random Drop here for more fun, or give the players to land on whose neigbhor they want: Zipangu, Lescatie, etc... ?) Remember, you're not the only one affected by them, but your scientific progress might affect them as well. (If you ask me, this is probably the hardest I'll ever do, cause even the Demon realm has not just tens, but hundreds of different factions and I have to program their leaders on what they think of you and their fellow Lilim)
