Which game to mod? Thread

Hei guys, i started learning java a while back and am constantly at it, creating all kinds of stuff with it. I have 2 games in my mind, i played both extensively for 100s of hours. First game is rimworld and the second is Minecraft, both of them can be modded to their deepest core. Now while i already have over 1 year of experience in Java, i tend to create a minecraft mod(i already have a theme and all the features planned, but this applies to both games..). But everytime i think about "now ill get to it", i always have the feeling im missing out on rimworld. Best case scenario would be to create mods for both games, but this would be to timeintensive since the mods for those games are pretty large scale. Also rimworld is written in c# and compiled in unity, but learning c# doesn't prove to be to difficult after looking at the code structure because there are a lot of similaritys.

So i really can't decide on which game

Which game would you rather play?

sorry for the english, not a native speaker

How about writing super small scope mods for each of them and base your decision on the experiences you made during the development? Every experienced modder/developer will tell you to start as small, because we all tend to start with too big ideas and then fail at them.
