this mod lets you edit savegames and replace portraits for all NPCs and companions with custom art. Replacement affects splash screens.
If you hate their dialogue and voices, you can use this same mod to edit your cash and purchase a roster of companions you get to customize yourself.
Question: 'Rule implementation' - did you try it turn based or real time? real time sucked in that game, but turn based is very good imo.
Consider looking at it again and using mods for companions.
