Gee Don Killuminati, I had never got that much praise before, I feel flattened, thank you so much :)
Concerning the difficulty setting the mod is meant to be played on is the Normal difficulty. People might find it a bit too easy, but I've always felt that Carmageddon were easy games. In Classic Carmas, in tier1 or in tiers where your car has not been upgraded yet it does not take too much effort to destroy the light cars such as the Countslash, whereas more armored cars can take more time (like fighting the Twister using the Eagle, for example). Given how different classic Carmas dealt with damage balancing, my aim was to make Max Damage "feel" closer to classic carmas, not make it just the same.
In Max Damage, the speed is almost the most important factor when dealing damage, which plays against the player. Opponents are much, much faster than the player car, so much that I reduced their speed to a 40% and they still are faster than a non-upgraded player car. Plus, there was the wall-ricochet effect that deals too much damage to your car, even after only being rubbed by an opponent, the game "tags" your car for an "x" amount of seconds in which you will be severely damaged if you hit a wall. It's strange because opponents do not seem to be afected.
Plus, opponent AI is way more aggressive than in previous Carma. I just don't get the "An opponent will always be chasing the player to keep him busy" thing, it does not feel right imho. I think using some kind of custom AI patterns for different opponents would be interesting, such as some opponents being more aggressive or passive than others. The sum of all of that (Speed = more damage, aggressive AI, opponents being always faster and wall-ricochet damage multiplayer) is what makes C:MD so frustrating to play in Freeplay mode, which is the mode everyone should play for a quick and satisfactory game, not seeing your credits into the great negatives by being constantly ganged up by fast opponents that deal too much damage to have any fun at all.
Anyway, the mod is still under constant tweaking in order to make it different for different players!
