Microsoft has defended the Xbox Live Games on Demand version of Halo 3 that went on sale earlier this week.
"When installed to the Xbox 360 hard disk drive, players may experience longer than average mission and map load times, but regardless of where the game is installed, gameplay performance is not affected," a spokesperson told Kotaku.
That tallies with what Digital Foundry discovered following the launch of New Xbox Experience in late 2008, where loading times for Campaign maps were around 10 seconds longer from HDD than DVD on average.
Still, whether you're waiting 46 seconds or 53 to kick off Sierra 117, you know it's going to be worth the wait. Unless you've never played Halo 3 before, in which case you should: it's like a cross between Lord of the Rings, Star Wars and Barney the Dinosaur.
