(Title corrected by a user) I mean, Mappy has a "lore". Dig Dug has a "lore". But I can't seem to find Bomberman lore.
"Bomberman has lore?" as a question would generally be some sort of surprise or suggestion that it goes against expectations.
"Donald Trump is a young man."
"Donald Trump is a young man?" -- response to a statement that went against expectations.
"Is Donald Trump a young man?" -- neutral, general question (if additional context or tone is absent)
