Dice games

I want to make some table top solo games that you can play with other people if you want.  

A journaling ttrpg 

A dungeon crawl

A high score game

They'd all be rolling dice to generate outcomes. It's hard not to want to combine everything into one for me. I need to keep them separate.

For a journaling ttrpg, that's probably the easiest. Roll dice to generate/stimulate ideas. everything else, loot, stats for you, enemies, equipment, etc are nice not not necessary. Story/role playing first. 

An example of a high score game would be Scrap! My big take away from this game is assigning an action for all your dice. I think it's best when there's a mixture of positive and negative results that the player chooses. Having to assign the dice you roll gives the player decision and therefore the "fun/play" aspect. 

Dungeon crawl is the hardest as stats matter the most and the more content the more replayability to an extent/degree. It's the most work and you want some degree of balance for combat.
