You know Rockstar Games presents Table Tennis? Is that game any good? Because I wouldn’t know.
Table Tennis relies very heavily on the player’s ability to see the color of the ping pong ball’s trail. If the ball leaves a green streak in the air, it’s got forward spin. If it’s got a yellow streak, it’s got backspin. That’s what it seems like to you, anyway: to me, there is only the blue streak and then three other ball trails of identical color which I cannot, in my wildest dreams, hope to differentiate between. There are very subtle visual cues to differentiate forward spin from backspin, but they don’t give the player the immediate visual feedback a simple color does.
When I tried to play Table Tennis the first time, I immediately noticed the color-based spin system and, despite my best attempts (in this context, “best attempts” means “continually hitting the downspin button and cursing violently when my shot doesn’t work the way I want it to”), I got my ass handed to me by my non-mutated friends.
