When I teach relativity, I offer my students extra credit for playing each of these two games. They capture rather different aspects of the structure of spacetime, and I think both are interesting and worthwhile. (As an aside, I fairly consistently wind up feeling a bit dizzy after playing all the way through "A Slower Speed of Light". It can be disorienting in a way that messes with my inner equilibrium somehow. Velocity Raptor isn't immersive enough for that to be a problem.)
