WRC World Rally Championship

A lot of people don't realise how significant this game was. Not only was it a competent driving game on limited hardware, but it was also the first to have an online leaderboard way before online multiplayer games were a thing on Playstations. During championships, the game would give a 6 character code that you could enter on to appear in the leaderboards. Sadly, the encryption was weak, the hackers underestimated, and the leaderboards were hosed with impossible times - a problem that was fixed in WRC2Extreme.
