Xbox Live competitor? Speaking to GamesIndustry.biz, Bungie's Lead AI Programmer, Damian Isla, had quite a few nice things to say about Infinity Ward's ridiculously successful shooter, Call of Duty 4: Modern Warfare.
Isla joins a chorus of reviewers in praising the game's single-player campaign for its tight pacing and scripting, praising the developers for doing "a hell of a job with their set pieces, of scripting certain moments that they were really sure the player was going to actually see and experience first hand." Though Isla notes that Halo 3's gameplay is heavily dependent on simulation (meaning in-game physics and reactions, not reality), it still "has a lot to learn" from Call of Duty 4's tunnel of fun approach.
With Infinity Ward's next project rumored to be a sci-fi shooter, it seems the studios might soon be trading places outside of the Xbox Live rankings.
