Pros
Pro First official US release
DoDonPachi DaiFukkatsu was released on Japan in the Arcades and on the Xbox 360, and then released in PAL regions as DoDonPachi Resurrection. While the EU version was region-free and thus could be imported, this is still a barrier to entry for many people.
There is also a mode which was previously JP-only, titled Black Label Arrange and referred to as Ketsuipachi, as it features the ship and certain mechanics from Cave's Ketsui as well as a re-arranged version of its soundtrack.
Cons
Con Near perfect port, but not 100%
Like earlier Steam ports of Cave games, the code is taken from the Xbox 360 versions of the game which did not feature an in-game counter for bullets and enemies, but instead slowed down when the number of objects on screen taxed the hardware. Modern gaming PCs are much more powerful than an Xbox 360, which means without an in-game counter keeping track of enemies and bullets there would be almost no slowdown, making these games next to impossible. Degica has addressed many of the concerns and instances brought to their attention by enthusiasts and implemented emulated slowdown, but some issues may and do still exist.
