The next strategy guides being developed include the following:
Now that Square has announced that they will be releasing a remastered version of Final Fantasy XII, this game will be next on my list. Scheduled completion is for the last quarter of 2016. Can't wait to get through this one!
Final Fantasy X-2 Remaster is on the list, but unfortunately it keeps getting pushed further and further back. It will be completed following FFXII though.
