All Followers at Camp
If you meet someone who chooses to come along with you, they should all be present in your main camp, which differs from your party that is an expedition able to camp independently. This way, you can travel and grow together as a larger group and take expeditions to go on individual companion quests and adventures.
Narrated Segues
One of the key elements of the BG experience is the digital GM narrating key transitions in the story. If this isn't present, you are not at all giving love or respect to the series, IMO.
I could get behind TB given the following:
- fixed-isometric camera with zoom, able to rotate in fixed increments (90 degree for tile, 60 degree for hex), but a free-cam that is not bound to a player
- the grid must be part of the underlying design of the environment such that exploration always keeps you on your toes and looking for advantage
- proper range for ranged weapons, none of this 13m crap
- proper D&D cover mechanics
