The biggest casualty was the music. The One version had a dynamic soundtrack that swelled as you neared a festival site. The 360 ISO couldn't handle real-time audio mixing.

Players would never know it was the console gasping for breath, not a DJ mistake.
It worked. But it came at a cost.
The Xbox One version had hundreds of drivatars—AI clones of your friends. The 360 had no cloud processing power. So Mack programmed “The Pack”: 12 aggressive, cheating AI drivers whose sole job was to rubberband ahead of you, then stall dramatically to fake a challenge. They weren't smart. They were theatrical.

They just wanted to drive a Lamborghini through a French vineyard. So Mack wrote a script that pre-baked the audio transitions
On the Xbox One, that drive was a golden ribbon of possibility. On the 360, the engine would hit a memory barrier so hard the console would hard-lock, the fans spinning down to a dead silence.
“That’s not development,” Jen whispered. “That’s archeology.”
