Well the plot was even thinner in D1 than it is in D2. Unless... You read through all the grimoire cards. There was a lot of material there but it just wasn't in the game. D2 feels the same way. There's a ton of lore out there to explore that's pretty interesting. I just can't understand why they wouldn't use more of it in the actual game. My name is Byf has a lot of good lore videos and he actually has a pretty lengthy one that sums up all of D1 you should check it out. Also Beard Grizzly and myelin games have pretty good lore videos also. It's a shame though that lore videos by you tubers can catch you up on lore and get you more excited about the story more than the in game story.
