Just like mobile cashgrabs "house rules", just like sword coast legends "house rules" and so on.
We don't have a decent D&D adaptation since nwn2(2006) and even nwn2 requires heavy modding to be faithful to P&P(spell fixes and warlock reworked are must have mods). There are so many cases of "change as they see fit" producing worse effects.
The pen and paper version uses imagination for fuel, and the operating system is the human brain of the Dungeon Master. Any adaptation away from that system is going to be more limited by definition. A computer game requires that all the content and the systems be put into the game, into a sealed box which cannot be modified on the fly. Making a fun system has to be the priority, because there is no DM to smooth out the wrinkles and add in totally original content.
