Last as in, by its release date, not as in "I bought Mario Galaxy 1 in 2014", though I suppose you could add that too if you want.
For me, Epic Mickey 2, 18th November 2012. Bad choice; I enjoyed the first one but the second sucked the sweat off a camel's bollocks. Should've quit after the excellent Project Zero 2 Wii Edition in June 2012 and ended on a high note.
Bet with Liquidlaser: I say PS5 and Xbox Series X will sell more than 56 million combined by the end of 2023.
