I'd really like to see sam telling lores and stories of characters, for example "Whats -name- lore in the game -name-"
That would be really interesting and fun.
I believe that your idea is amazing and should be added. Also, I belive Sam could give information about the games setting and lore ect. For example Rainbow Six: Siege is based off the book Tom Clancy 's Rainbow Six from 1996 (?)
