Have you played with Mario Builder 64? I did a game jam with it last month and found it really delightful. You're pretty restricted in what you can do - practically no coding, just pulling in components from the Mario 64 base game - but in exchange it's really simple to get a whole level up and running in like an hour (our whole game jam was 2 hours long). My level design skills are pretty weak. Being able to partially compensate for that by getting built-in nice character movement, enemy design, etc for free was really really nice. If I wanted to do more 3D stuff right now I'd almost certainly be using something like Mario Builder (I think stuff like Doom custom maps get at a similar idea).
