He's not required to. It's the OP's individual choices: if he doesn't want to see a new Pac-Man show, then he doesn't have to choose it.
I think there may be some confusion regarding the topic of this thread. I think the OP is asking which video game series (read: franchises) should get TV shows, not which old cartoons based on video games should be remade. Castelvania, Streets of Rage and Crash Bandicoot never had TV shows either.
Idly, most of today's video games are so elaborate with their cinemas and whatnot that one has to wonder if many of them even need TV spinoffs, especially the ones which have several entries in a series of games.
