Uniqueness: Before DHI, I believe the mock MMO was a truly unique idea. DHI is very decent. I enjoy opening dungeon portals, gathering treasure, and many other things about DHI. DHI would be improved by letting you save anywhere. DHI is about average length. DHI caused me to want to own the series. X, Circle, Triangle, & Square: DHI uses X for Attack, Confirm, & Talk. Circle is Cancel, The Triangle Menu allows you, the player, to access Skills, Items, etc. Square accesses a menu that allows you to control things connected to your party members except your character. Basic Strategy: In DHI, you can avoid enemies by avoiding the portals found in each field and in each dungeon. Avoiding enemies comes with a cost. Usually this includes a lack of experience and/or level. I have found that most if not all field portals can be avoided at little to no cost. However, most if not all dungeon portals must be opened or it is greatly beneficial to open dungeon portals. In many cases, it is also beneficial to Data Drain enemies that are too tough to beat otherwise.
