Dracula wasn't defeated in a generation. Rogue Legacy is a heavily Castlevania inspired game where you explore through an evil shape shifting castle. While you only play as the successful Belmonts in the Castlevania series, surely not every generation was that competent, and in Rogue Legacy you play through all the generations that didn't make it...
Specs
Pros
Pro You don't lose purchased loot
The upgrade system in Rogue Legacy works by spending the money you gained in the last level (you lose all your money when you start a new one), with upgrades passing down through generations by being either upgrades to the family manor, or family heirlooms. This way even when the player dies (which happens a lot) the player will not loose their purchased items allowing them to continue without starting completely over.
Cons
Con Something's off...
Eventually you realize that when you beat the game it will mostly have been because you played it so many times that you got all the upgrades rather than that you played it so many times that you got good at it.
A good roguelike gives each play through equal chance of winning and rewards good game play rather than more game play.
