In short: Guitar Hero + Youtube = TubeRockers. My first rhythm game in flash.
It’s really very similar to other games out there in terms of gameplay, scoring, etc. You should still give it a try as it uses YouTube videos for music and background. This means two things. The game looks cool (in my opinion) Possibility of new tracks is endless. Who could ask for more? (Actually you could ask for a smoother, less choppy gameplay on systems that hasn’t got a dual core cpu) Right click and select “low quality” it helps.
