Valkyria Chronicles has started selling. In fact, its April sales were the equivalent of its launch sales. That's an increase of 400% over March. There are a number of reasons for that could be cited as the reason for its increase: DLC, online contests, and most importantly, a price drop.
We'd just like to clarify at this point that we've still never seen Valkyria Chronicles for sale in a shop. Perhaps they could release a new version, with trophies and all the DLC included? Perhaps it will sell better now that it has such a wealth of word-of-mouth behind it?
