That's it. All games require you to suspend your disbelief. The trick is making the player care enough about what's going on that they don't care about the inevitable weaknesses. And as I think I said in the other thread, we can't forget what an amazing job ND did to make us care about a game in which you are constantly nannying a companion. In other games that can be a real pain in the backside, even for short sections (note: I haven't played Bio Infinite).
I'm trying to play through again on Hard. I don't think I'll keep it up for long (I like to enjoy my games, not struggle), but because I'm having to be more careful and sneaky, I am noticing more silliness from the AI.
However there's a part of my brain which tells me that's just the game showing me what it
thinks my companion would have done, which is why the enemy AI didn't spot her run past them. In 'reality' I know she sneakily followed behind me, taking great care.
Obviously though, being able to think like this requires you to be really immersed in the game. I never had a problem with that one the initial, and rather contrived, tutorial sections were over.
While I'm here, I'm pleased to see that Charlie Brooker finished this last night, and rates it highly. His stance on computer games is usually pretty well thought out.
