All in one Solo RP?

Hello, folks.

Currently, I am trying to return to solo rp. I even have a starting point in the story all ready to go. I am, however, a bit trapped in the system department, and I've been having a lot of attrition between thinking it up and actually start playing.

After some thought, I figured out that my problem is that I do not want to be opening a thousand pdfs while I play, because that would feel more like work and less like play. I want a system that has everything in it: mechanics, tables, random events, hexcrawling, everything.

Of course, Ironsworn and Starforged are the first ones that come to mind, I've played those two before and although they're awesome, I think they may be falling a bit short of what I want right now, specially because Ironsworn lacks any actual hexcrawling mechanic, and I want to worldbuild through my amnesiac character's eyes as he discovers the world/universe/whatever he's in.

I thought about going with MGME, which could probably deal with everything, but I can't figure out a decent way to make it work for combat.

Do you guys have any recommendations?

PS: I am aware that the main (and probably the only correct) recommendation would be "just start playing and stop looking for the perfect game", but I think that worrying about this for at least one full month is an intrinsic part of the process.
