is it possible to mod the game so that critters change targets in their turns? it's sad when your NPC kills a guy with one critical, than wastes all his remaining AP because the game prevents him from switching targets.
Indeed, this really needs fixing! But I think it may be impossible (or nearly impossible, taking too much efforts, like adding a new stat to SPECIAL and including it in the game so good like it was originally made).
What if the game has a critter's current target stored in memory? A memory editor in background may be able to change the current target to something else. And if you could add a little logic into a program that can determine which other targets there are then thats it.
