Aside from war games, you don't see too many titles based on true stories. Secret Files: Tunguska from Deep Silver for the DS and Wii (a port of the 2006 PC version) looks particularly intriguing; it's based on the true but mysterious event of the 1908 Siberian explosion. Amazingly, the DS version seems to look just like a shrunken down version of its Wii counterpart.
