Shin Megami Tensei IV: Apocalypse
With the first installment being such a critical and economic success, Shin Megami Tensei publisher Atlus launched a sequel three years later, also on the 3DS. The fairly perplexing naming pattern stems from the fact that Shin Megami Tensei IV: Apocalypse takes place in the same post-apocalyptic universe as the previous game but in a different chronology (and featuring a new main character).
Though many of the features and monsters from Shin Megami Tensei IV were carried over to Apocalypse, critics complimented the game for adding a lot of quality-of-life enhancements to the systems, giving players a more polished experience. Unfortunately, Apocalypse's sales were substantially lower - maybe because players were puzzled by the title, which gives the idea that it's an upgrade or expansion rather than a totally new game.
