May I suggest my recent 3 ttrpgs? They're all solo-journalling rpgs, and no prior wetland knowledge is required!
'so, you're a small patch of moss in a big bog...'
a micro solo rpg about being moss facing the inevitability of becoming peat. explore grief, mortality, and inevitability.
'the bog eternal'
a game about being a bog fighting against people trying to harm you, with only your natural traits. totally not an allegory for anything beyond that... I'd totally tell you if it was, deeeefinitely not an allegory for transness, nope.
'you're going to your ideal wetland'
a game about creating and traveling to your dream wetland, emotions about climate justice, and naming that wonderful place.
