PSO1

A completed game like PSO1 is a lot easier to speedrun. You have all the content available, so categories are much easier. PSO itself is seperated into each episode for its speedrun but theoretically it would be possible to run a '100%' i.e do all available content from each episode on a base account. this would take 300+ hours easily, as the game is slower paced and is so long and would require grinding etc. This would involve doing Episode 1, 2 3 and 4. a huge amount of time for a realistically achieveable goal. PSO1 would also have the 100% items idea, which would also run 100000+ hours, due to it having 1/300000 rate on multiple drops. many people have played the game for 10+ years on  SEGA-accurate servers and no one has ever come close to achieving this. so in essence, that sums up the categories you could undertake in the game,
