It seems that Harmonix isn't okay with the recent trend of rushing out a game before it's ready and has delayed its musical action title, Amplitude.

Polygon reports that the release date for Amplitude has been pushed back to next summer instead of its original launch window of March. Harmonix's reasoning for this delay was simple -- the game simply isn't ready.

"This is our first time working on PlayStation 4, and it's been a big learning experience for the team," a Harmonix representative said. "We've put a lot of work into our proprietary engine to support some of the new, awesome content we're bringing to the reboot. These factors combined have bumped production out a few additional months."

"With Amplitude and our promise of open development, you've given us the opportunity to create the game we want to make and, more importantly, make the game that you want. In order to meet that goal, we don't want to cut any corners, and we want to stay true to our vision and deliver the best Amplitude experience possible."

Harmonix started Amplitude's Kickstarter in late May and raised a whopping $840,000+ for its newest rhythm-based game, which is now slated to arrive in the summer for PlayStation 3 and PlayStation 4.
