People are seriously overrating Zen and VP, while seriously underrating
TPA. Zen is a shady company and none of their releases feel even slightly like actual pinball at all. Meanwhile, all work done in VP is constantly held back by VP itself, no matter how many updates that wretched old thing gets. These are not good alternatives and people should stop recommending them all the time.
TPA is all we really have. What
should be happening is that we should be boycotting Zen in TPA's favor, but considering that everyone hated
TPA at every point during its life, that seems unlikely. If
TPA goes, digital pinball goes, unless and until someone is willing to appear to put Zen and VP in their place. That seems unlikely too, so digital pinball is basically doomed, while real pinball is becoming increasingly harder to access.
