Well, as far as I am concerned, the game will not be in a playable state for me without some critical mods. So modding tools are a must.
Oh, bold claims. Please, elaborate.
Not a "bold" claim at all. I, and many others right here in this forum, have pointed out the things we consider to be major flaws in the game. So nothing new or surprising. It is simply a case of some of us rejecting certain game design choices Larian has made which we consider to be wrong. For others, may be even many others, those design choices may be right. But that does not negate the feelings of those of us who consider them to be wrong.
For me, then, I could not play BG3 (as it currently stands) without mods for certain things, two that are critical and a third that would be nice to have but is not critical. The critical mods would be: (1) a mod to increase party size to six, and (2) a mod to keep alive and carry over companions not in my active party into Act 2 so that I can have spare companions in my camp throughout the game.
The third non-critical mod would be to allow me to pause the game during exploration.
Obviously as someone who strongly prefers RTwP combat and who considers TB combat to be trash, a RTwP mod would be amazingly awesome. But such a mod I am resigned to accepting as something that will never be made.
