That poorly-spelled tombstone was saved on a disk that ended up being widely pirated and appears on almost all archived copies of the game, becoming nearly as iconic as Oregon Trail itself
Free Game Friday 2/7/20: The Oregon Trail
An edutainment classic for the fact that, based on history or not, it was also just a damn fun game. It blended in elements of roguelikes with its randomized events and an emphasis on challenge, daring the player to start as a poorer character for the payoff of a large score multiplier at the end. There were multiple pathways and some twitch gameplay segments too (hunting and sailing down-river), so those more used to arcade action had something to like too. Just a fun game to play in general, and the fact that it's had iterations dating all the way back to 1971 and continuing to this day speaks to its timeless charm.
