If you wailed when you heard that Rock Band 4 wasn't coming to the PC, it's time to wipe those tears away -- you now have a chance to make it happen. Harmonix has kicked off a crowdfunding campaign to bring its latest music game to Windows systems through Steam. So long as the company reaches its $1.5 million goal by April 5th, you'll get a version of RB4 that transcends what you can do on consoles. You'll get to directly sell your own songs through Steam Workshop, for example, recreating Rock Band Network without all the overhead. It'll support a mouse and keyboard outside of songs, too, so you won't have to fiddle with your plastic guitar just to change settings.
