>>11858126>HDD was not needed for 99% of the games, just a foresight by Sony. A strategic foresight that didn't pay off.The US version was neutered to fuck because of the PocketStation and Everquest.
Due to the mess that was games in the US having PockerStation features and sometimes locking content behind them, but Sony eventually deciding not to release the PocketStation in the US after all there were many people not happy about the situation. So in response Sony declared that publishers may not add features for hardware that is not available in that region.
The PS2 HDD comes out in Japan, it includes software to download demos, play music, view photos, and many games support it either for installing for faster load times and/or for using it as a massive memory card. FF11 is basically the only game that requires it.
However, Sony was working on their own PS2 MMO, Everquest Online Adventures, which did not need the HDD, but it was nowhere near ready to launch. So they kept delaying the release of the HDD outside of Japan, for years, to the point where S-E stopped bothering with their plan to release FF11 on PS2 first and released it on PC first in the US. Due to these delays the HDD was pretty late outside of Japan, so the software to do all of this was never released (even though there was several pages in the HDD manual telling you how to use it) and many many games had their HDD support stripped outside of Japan because of that PocketStation rule. Then eventually they released a slim version that removed HDD support altogether because people were using it for hacks, much like later PS1s removing the parallel port.
That being said, the Xbox came out just a year after the PS2 with Xbox and a built in HDD so...
