Platinum has up a massive blog featuring an interview with Hideki Kamiya. The blog takes a look at Hideki's career, as well as all the different games he enjoyed while growing up. In part of the interview, Kamiya discusses his affinity for Tetris Attack.
Turns out Kamiya and a lot of other devs played Tetris Attack a great deal back during his Capcom days. Kamiya was involved with development of the original Resident Evil, but it seems sometimes Tetris Attack would get in the way of dev team's work!
When I was working on Resident Evil, Tetris Attack was really popular at the office. We’d play against each other every day, to the point where work got ignored and Shinji Mikami had to put out an order banning Tetris Attack.
I'm sure there had to be a delay or two for Resident Evil. If there ever was, now we can blame some of that on Tetris Attack!
