It does have Danny Phantom and Invader Zim in the base roster to rep the 2000s, but it's interesting how all of the "modern Nick" content in it is just from series that never died (i.e., SpongeBob) or old IPs that have gotten reboots or will soon be getting reboots on Nickelodeon (i.e., TMNT, Rugrats, Garfield)...
I'm also still trying to figure out why they made nostalgia such a big deal in the Apple Arcade game, but maybe I just don't understand the target audience of Apple Arcade? I associate the service primarily with parents trying to placate their children, but maybe this is too harsh....
