I made
a simple tweet expressing my frustration at how the most easily accessible version of Sonic Adventure (SA DX on PC) is also one of the worst versions of the game, and the wonderful @Merlin comes in with a genius summation of my feelings on the situation.
I could go on about how the Dreamcast version of Sonic Adventure is the best (forgiving slight things like unskippable cutscenes and framerate that isn't the best), but instead it's best to point you to the
Dreamcastify website that goes super in depth into the issue with an attention to detail I admire. It's also where the above game screenshots are from.
