Post those games that never got to see the light of day (i.e, cancelled games) and lament over their losses.
The worst offender for me is Heaven Variant. A true spiritual successor to one of my favorite shootemups as a child, I would have played this over and over to get a perfect score. Speaking of perfect score, it has a badass soundtrack, which you can enjoy here. Fortunately, the studio is reusing the concepts introduced to make a new shmup, pretty much starting over, unfortunately without the 3D graphics, but I'm not complaining. I'll miss Heaven Variant though.
