If Streets of Rage 1 2 3 was your thing in the 90's, then you'll love Streets of Rage 4. Words cannot describe how excellent a game this is. The developers truly understand a Streets of Rage game. All the great parts of the series are still here and the improvements feel like they come from fan feedback.
Visually, the game is a masterpiece. It didn't look like a Streets of Rage game to me until I played it. Once I got into it and can feel it, it nails it. The sound is very well done too. Soundtrack is great. Easy purchase.
