Game Center CX in loving detail
Every element of Game Center CX accurately parodies Japanese retrogaming: Rally King SP is a remade version of the (also fake) top-down racer Rally King with branding from a fictional ramen company. Product tie-in games like this were common in Japan at the time (though they've all become frustratingly rare now!) and in fact, some, like Gradius: ArchiMENdes Edition, were actually given away by ramen companies.
The "challenge" focus of the game actually sort of makes Game Center CX a bit more modern. Rather than simply completing levels, you're fulfilling objectives. It's almost mission-based, but in an interesting way.
