@rainwalker:
- no stat rolling. Players just re roll until they like the result.
Point buy system is better for balance.
Maybe add some pre generated chars for those new to DnD ( not sure if you could customize the origin chars when you start the game. I hope you can, even if their look and starting class are fixed)
- regarding spell, items and character creation: just follow the DnD 5E rules
- I do not think there will be rtwp.
If you chose action, bonus action, reaction and positioning for a full party, you pause every second anyway.
In the IE games you could only attack, cast a spell, use an item or move.
In BG3 even martial chars have lots of options for actions, such as throwing enemies around.
