If you though Double Dragon 3 on NES wasn’t good. Check this out.
About a minute in there’s a store that sells things using the actual arcade cabinet coin op, which could mark this game as the origin of in-game microstransactions. It’s funny how so much changes after 25 years yet everything stays the same.
Wow! I never saw that in the arcades. Note that this was due to DD 3 being broken on release. It couldn’t be beaten normally so they had to let the player buy those cheats. Perhaps this explains the Free-to-play and mobile games. Most of them are ‘broken’ so they make you buy stuff in order to beat it.
