This came from my post in the Campaign replayability thread.
If ANYTHING, an AI director is absolutely mandatory for ensured maximum enjoyment of multiple Campaign playthroughs, even if it means sacrificing a bit of the graphics to compensate. If anyone has played Left 4 Dead, they know what I’m talking about.
An AI Director is something that alters the game you play as you play it. It can spawn enemies randomly, spawn weapons in random locations, health, etc., etc. It even sometimes alters the layout of the map (ala Left 4 Dead 2), and picks different pathways for you.
Why is this needed? To put the Campaign gameplay enjoyment, RIGHT UP THERE with Matchmaking. Using a system like the Director adds infinite amounts of replayability to the Campaign. The unpredictability of Left 4 Dead is what makes it exhilarating and extremely fun. Halo has had this somewhat, but it only affected enemy ranks, and somewhat what the enemies dropping out of scripted dropships were.
I think it would be a very, very nice deviation from the regular Halo formula. If it was implemented, there would still be scripted enemy events, but here’s how I think it would turn out.
The AI Director would obviously create his own unique encounters time and time again by spawning mostly random enemies and weapons around that part of the map where you were in, partially based on how well you were doing. Occasionally, he’ll spawn a dropship or a wave of enemies when you’re not expecting it, making for some pressure and tension. He’ll spawn the rare allies and health/upgrades on Legendary when you’re doing exceptionally poorly as well.
The higher the difficulty, the more unforgiving he is. THIS could be a SOLUTION to Legendary’s current formula, which is to just give enemies ridiculous amounts of health/shields. The AI Director would make them more aggressive, and he would have them actually rush your position en masse on Legendary.
Replayability is everything when it comes to games today, so other than a hypothetical, tiny drop in the graphics to compensate for all of that live processing, there’s no reason not to implement this for the Campaign. Sure’s there’s Firefight which is random itself, but the Campaign keeps you moving; you’re actually striving toward a goal, not just racking up points and surviving in one position.
