My Idea for the Gameverse/Madhouse! DMC Timeline
1 AD - Sparda rebels against Mundus, Sealing him and Makai/Hell in Temen-ni-gru by Perfect Amulet, Force Edge, and Lady's Ancestor
Somewhere in the early Centuries - Ruled and fought alongside humans, returns to Makai/Hell to fight Argosax and Bolverk
Late 20th Century - Meets Eva
October 27th, 1973 - Vergil and Dante are born
Around late 1970's/Early 1980's - Sparda disappears and died
1981 - Eva gives Vergil and Dante halves of the Perfect Amulet on their eighth birthday, Eva is killed with Dante and Vergil separated
Mid 1980's - Dante lives in Morris Island under Anthony "Tony" Redgrave, befriends Ernest, left due to demon hunting Dante/Tony
1991 - DMC Novel/DMC 3 Manga - Opens a shop with Enzo Ferino, Nero's Birth
1992 - DMC 3 -> Names shop "Devil May Cry"

Note: May not be exact, but it is the most I can do through some research. I used a popular opinion of Dante being 28 in 2001. I hope this will suffice.
