id Software co-founder and chief mad scientist John Carmack revealed during the keynote address at QuakeCon yesterday that his studio had to cease developing mobile games to focus on Quake 4. Carmack said that it had to close its mobile game operation and shelf whatever iOS projects it was working on to focus on other important priorities:
"It saddened me a lot to because I loved doing the mobile work," he said. "It was fun, it was fun for the company, it makes money but it's not a grand slam sort of thing."
"I do hope we get back to mobile in various ways in the future, but the big, real aim is blockbuster triple-A titles," he added. "For Id, that means Doom 4."
Carmack went on to say that some of the mobile games team was shifted over to the DOOM 4 team.
On a slightly related note, two id Software games for iOS are now available for the discounted sticker price of $0.99: Rage HD and Doom Resurrection...
id Software is owned by Bethesda Softworks, a division of Zenimax.
