In honor of Conatus Creative hitting their Kickstarter funding goal for River City Ransom: Underground, here is a medley of RCR music by Entertainment System. Check out some more of their work, they've done all kinds of cool covers/medleys/mashups/whatever of various classic video game tunes. I grew up on 8-bit NES games, and hearing those tunes come alive really brings me back.
There's still a little time left if you haven't donated to the RCR:U Kickstarter, and there's a stretch goal that is definitely within reach. Check out the link to the project page for information on reward tiers, stretch goals, etc. Also, check out the introduction video below for a bit of gameplay footage.
