But things actually got crazy much earlier with GTA: San Andreas.
Games like these didn't need multiplayer-they weren't meant to have it-but got it anyway, thanks to the mod community. But this final mod-a hack, really-is easily the most mind blowing I've ever seen. This is Ocarina of Time with four-player co-op and it runs on a brick-and-mortar Nintendo 64. Development started around March 2019 and got hold after a update that broke progress to that point. Wrong answer buzzer noise! All the laser-blasting, perk-picking adventuring of the Wasteland can be played with others on dedicated servers.
