The "party" can only be controlled as a single character with multiple abilities.
This is wrong. It implies that at any given point, you can make use of all your characters' abilities. And it's wrong.
I'm not sure what you are trying to say, but only one ability can be activated at a time, only one character at a time, whether in Dungeon Master or Skyrim. It's the same material effect.
You choose to either cast a spell or swing the sword, but not both at the same time in Dungeon Master or Ishar or Skyrim or Captive. All those games play fundamentally the same.
You're a blob, apparently. Skyrim the blobber.
Certainly not out of the question that abilities can be muted/silenced/disabled separately as well.
Wish I could disable your ability to post
The ignore feature is broken for you?
Snowflakes and safe spaces.
