Be nice if they fixed whatever bug they have on the Switch 2 that means every replay I previously downloaded[0] is unplayable and further that every time I now try and download a replay, the game crashes.

But then it'd also be nice if they fixed the "game crashes randomly when joining games" bug too.

(To give them credit, it doesn't now take 5 minutes after waking the Switch 2 before Rocket League reconnects me to the Epic servers like it did a couple of months ago...)

[0] Also the stupidly low limit on how many you can download - it's my storage cost, not yours, wtf.

also trackmania, and it's a common way they use to catch cheaters as pb on leaderboard have inputs

Replays are very common in fighting games as well, rollback netcode gets you most of the way to a replay system already (replaying game state from inputs is a core requirement for online play)
