I heard that you want to make this game like "do whatever you want" game so you should try elona plus and learn from elona If you want to make game like that and also GIMME MOA of interactions and implement dialog screen where you can choose what you want to say, also you need to add alignment(Who doesn't want to be evil
),multiple endings but that much later, add skills which player will learn by doing stuff linked to that skill,Random events- I need that,implement crafting and building,later in game in specific dungeons player will find schemes of guns,rifles and all that good stuff,random artifacts this is important too,random quests, jobs (like quests but they could be done infinite times),and after defeating the main boss in the game you are teleported to another world (but this time deus ex like world) where there will be illuminati,aliens,future equipment,new stuff to discover,new skills,no gods (only factions),cybernetics and of course the MUCH BIGGER new world.
And also one of the most important things factions, you can join every faction from super evil through minor evil to ultimate good factions have they own equipment schemes,magic,and everything
You can create your own faction,you can create your own flag,manage armies,raid cities and other factions and then rule the world.
If you will be able to do this this roguelie will be better than every roguelike and you will have a lot of money from donations of course AND DON'T EVEN TRY TO GET THIS GAME ON STEAM AND MAKE IT NON-FREE!!!
