So, there are some very long answers to this one, but this is a situation where accessing my notes would be awkward.
As a short answer, yes - there are two main games I'd like to be in.
The first as an exploration of what a failed legacy means and just generally being queerer than anything in the 90s could have been. A low stakes plot about rescuing a friend with benefits who likes being kidnapped, from another friend with benefits who likes playing the role of big bad. 1
Something simple as an introduction, with the use of various transformations for platforming.
The second is the true passion project; a very timey wimey plot about having to reconstruct the regular timeline by exploring (legally distinct) versions of the roads that were never taken in games.
Things such as F•STOP (aka Portal 2 without portals), or Dinosaur Planet before it got reworked.
A different form (or at least outfit) for each level, allying with characters from each game - and a finale with recreating some of the most well known final bosses except with the roles switched so now the player and me are trying to avoid being spun round by the tail and thrown into either a bomb or the airlock

coincidentally this used to be our headcanon about mario, peach, and bowser - even if we're generally more on the bowuigi train these days
