Pokemon Red. When Piracy wasn't a problem before, a local game shop was selling pirated Gameboy games for PC, in it was Pokemon Red. It had a bug at a certain area where you can't proceed anymore. But as kids, we just kept repeating the whole thing, and even leveled up a butterfree to 99, ridiculous I know. But kids had no concept of 'being fed up'. The next month our aunt bought a gameboy color and pokemon cartridges and the rest was history.
