Came up with an idea. Let me know what you guys think:
World Renowned Theif Escapes Prison
It is rumored that he has stolen many more artifacts since his escape.
The police have been struggling to find clues to where the theif has gone and where he has taken the artifacts.
You are a Detective called in to help with the investigation.
You receive calls throughout your investigation to lead you to various clues. You are faced with many problem solving puzzles. Memory also plays a key rule in solving this case.
Witnesses give you cloalls aswell when you meet up with them. Some of them may call you or leave you an email or letter.
In the theif’s mansion is where he has stored all the artifacts that are stolen; hidden all over the place.
The mysterious caller that gives you clues throughout the game, you find out later in the end is the theift himself. He loves a good chase and only steals for that reason along.
The game is more of an implicit educational video game. The players are unaware of it being educational, though that's the intent of the game.
