It's been 5 years since this thread was first opened but for something like a 100% ryu book run, I would suggest utilizing a save file-- play through the intro and then wait until at least 15 hours have passed (just wait around either in the first dungeon with orca, or right before you can make your first save, or wherever), save at the very first opportunity, then have the run start from choosing the load file with 15 hours on it! It wouldn't include the very intro, but it would be a true 100% run without having to be 15 hours long Of course, to be a valid run, you'd have to not opened any chests, destroyable objects, or collected anything The issues are with the couple monsters you have to fight, the portals you have to activate, and the chests you have to open before you're able to first save the game (in the tutorial dungeon with orca) But I think if all the start conditions are the same (2 boxes, x number of required monsters and portals, 15 hours on the save file with no story progression past the first save opportunity), then you could call it a 100% ryu book run
