It would be nice (and probably very simple) to have an option to select a low loot level. To use DOS2 as an example, perhaps disable all non Unique loot. Also, perhaps fill the loot tables with more craftable components so that instead of getting no 'reward' for a majority of encounters, you can occasionally get pieces to craft something.
Or you could simply use the DnD 5E rules because
- The game is announced as a game based on DnD 5E
- Creating a new system costs time and money that would better be spend elswhere, such as more areas, quests and characters and most importent more bug testing.
Creating a new system will produce bugs and balance problems and then you will need more time and money to fix it.
I am NOT against inventing new mechanics in games, else we would still be playing Pong all day. But a game that is based on an existing system (DnD 5E) is the wrong place to re invent the wheel.
