the annual
Tokyo Game Show was held in Makuhari Messe at the end of last week. I have yet to attend the TGS myself, but I believe that the participation of the 3 mobile carriers is a relatively recent phenomenom, indicating just how important the mobile gaming industry has become. and from reading the reports, i get the impression that each of the carriers expect gaming on mobile phones to become an increasingly lucritive market in the future.
DoCoMo
DoCoMo were promoting their 'chokkan games' that use motion-sensors inside the phone to detect movements to control play in the game. they also introduced 'next mega games' that will be available on yet to be released handsets, including titles such as Bandai's popular Gundam series.
au
au's booth at the game show centered on an upcoming title 'Metal Gear Solid Mobile' from KONAMI. it is the first in the series to be especially developed for a mobile. the price has yet to be decided, but it is thought that a demo version will come pre-installed on the soon-to-be released W53S. special editions of this phone with colloboration 'style panels' were also on display.
SoftBank
from the reports i read, it would seem that SoftBank had the most impressive booth of the three networks. they introduced 'wide games' compatible with AQUOS keitai 912SH, of which titles included StreetFighter Zero, BomberMan 3D and Tekken 2. They also announced 'tada games' which includes 32 titles that will be free of charge, and also a high-speed online game service that will launch in December. 'yosou guy' who I quite like from the SoftBank TV commercials also made regular apperances as Darth Vader.

I have posted an
article on QR-codes before, but its the first time I have seen a (temporary) tatoo QR-code. I thought that quite a fun and novel idea.
