Well,
Rollerball is about a dystopian future in which the sport is sort of a placebo for wars, and one top player decides to go against the system.
The Running Man is about a future US dictatorship (or something like that?), with the show as a means to control the masses. Dystopian? Well, of course.
Nitro Ball, on the other hand, features a TV show in which an ex-cop (player 1?) and an ex-Navy Seal (player 2?) have to kill/dunk goons and collect as many items for money as they can. The game's atmosphere is deeply humorous and hedonistic, down to the brilliant OST, and the endings for both players are definitely positive (hint: they get the money and something else

). I remember that AF! has a similar show, in-universe, that has the same "we're in for the money and the funny ultra-violence, and now please smile for the camera!" tone. Dystopian? AF! probably, but with a laugh.
Nitro Ball...well, not if you 1-CC it
This Sunday we are going to discuss a classic shmup, however, so we will leave the ironic commentary on hold for a bit. I need to reshuffle plans a bit, but hopefully I can release
Nitro Ball by the year. Aside the pinball-free scrolling shmup hybrid form, it features lots of scoring opportunities and the extend/suicide mechanic as a rank/score control mechanism. But all in due time, of course

"The only desire the Culture could not satisfy from within itself was one common to both the descendants of its original human stock and the machines [...]: the urge not to feel useless."
