@allison I personally never played it. I only know of that game because of those hidden messages. I assume that's what the game is actually mostly known for. It taught me that there are some things intentionally left hidden for hackers/data miners to discover.
Sadly though, it rarely happens anymore because games are pretty much data-mined day one and anyone caught doing something like that not only risks losing their job but risks getting a decent job ever again. It's a true relic of a different time.
