That does look cute Although I don't care for the intro theme from the video. It sounds too generic. Heck, even the singers said it was a dumb song, lol. If anything this game should utilise the original River City theme, kinda like how Double Dragon Neon did.
Generic? I haven't heard any beat 'em up with a theme as energy overflowing, fun and awesome like this one. Sure, there are iconic soundtracks with memorable themes like Double Dragon's, but River City Girls theme to me is perfect for it and more catchy than most themes out there. The song is so good watched the trailer more times than other trailers I rewatched cause their theme was so great.
RCR's theme is dated and not adrenaline pumping, it doesnt have the oomph, fun, motivational, and badass attitude RCG's song/theme has.
