I'm really good at taking other people's skeleton ideas and fleshing them out, or substantially improving on complete ones. I'd do great in a "writers room" setting. But my own original ideas have problems.

One part of me wants to make what I think of as "gamey" games. Just immerse myself in pretending to be Nintendo.

I wish I could start again from zero and forget everything I've learned or come up with and be in that state of just having discovered video games
I sometimes like to think of my games as someone else's games from a parallel universe, that branched off of our universe in a different direction sometime after I turned 15. Like what if, instead of Mario, DOOM, and Dune II being giant hits that launched major genres, some other game of my childhood did. Can I work out what happened in that other universe and bring back a game from that genre? What if Nintendo's big hit on the NES had been <X>... how did they follow up on the SNES and N64? Thought experiments like that.
I'm thinking of this because it's a bit like what you're good at -- working out a good logical conclusion from an idea that's already semi-started -- plus an artificial constraint that forces you to *not* take inspiration from too much at once. (In that the specific history of games in this other world splits off after the year 19XX, although they underwent similar technological innovations and improvements in craft.)
