I believe they can easily share more elements with each other at least.
Like a WL game that contains microgames inbetween worlds as interludes. We'd have a mini WarioWare within the game and typical modes you'd expect in the postgame. But...
hell no I feel like they should be separate I feel like each game has its own vibe (if they were merged together.. idk it would be kinda weird imo lolz)
@Goozu It was SSOOO fun duude I went to Disney world, universal studios and Epic universe!! let me tell ya I ate a whole ass krusty burger (surprisingly it was yyyummy) and I bought more cars (from the cars movie btw) although it was hot as hell...
