I've been playing that fan remake/revision of
Streets of Rage and it's well worth a try.
Criminal that Sega killed it off.
There's
links here (Win/Mac) and packages for
Arch Linux in the AUR.
Got it working on the latter with an xbox 360 pad (just had to rebind the buttons to something more sensible in-game)
He's basically taken everything in the original three games + some bits from Street Fighter + the kitchen sink = incline!
Some of the bosses/enemies are clearly inspired by Blanka, Sagat & Vega. (I fought the former in a cavern map what looked like it was straight from Aliens)
Options galore and that music.
You'd be very hard to please to not find something to like here.
You can even pretend you're smashing the readers of RPGWatch in the face with pipes, broken bottles and metal baseball bats.
A bit of
Youtube footage.
