8-Bit Rebellion was fun, but I don’t think we will ever see another game like it (although I would enjoy one myself, as well). There was supposed to be more added to the original game that never ended up happening, so I think the band’s interest in it kinda died off.
That being said, there were Hybrid Theory-esque designs made of each band member for the game that were never used. If I had to come up with some cheesy story for a hypothetical sequel, a time travel gimmick could be interesting.
We also never got full releases of some of the 8-bit songs they made, only 15 second ringtones. I really wanted that full 8-bit Numb
