Well in a local book store here, there are still piles of GA Magazines in dust
. GA's pricing strategy is certainly far from satisfactory as a new entrant. For the very few who have bought it, most agree that the extra dakimakura cover does not justify the premium.
Btw it seems like they did plan to release vol.2. In vol.1's editorial page it has been mentioned that vol.2 would come with a mouse pad. But then I am sure the sales figure can deter any non-determined team from releasing vol.2...
Regarding pricing, some time ago Dengeki was the only one at the 700 yen range. Sneaker was at the 900 yen range and Dragon was at the 600 yen range. Now they all have a very similar price. Competition is probably much more intense now.
