While built from the same mold as P3, P4 is more forgiving and much more enjoyable.
Positives:--------------------------------------------------------------
-Slightly Improved Graphics
-Social Links have direct impact on battle now. (**** Slap anyone?)
-Bite-sized dungeons means more time to relax and screw around. ->Each dungeon you visit has a unique theme based on each characters personality. Prepare for a psychological meltdown >:D
-While previous Megaten games have had a dark theme, P4 is a refreshing change with its "retro-yellow" theme.
-Great humor & Story Telling. ->Scooby Doo meets Deathnote
Negatives:-----------------------------------------------------------
-Quirky Camera angles during School/Dungeon areas
-The Calendar is missing so it may be hard to predict when "Foggy" days may appear. ->Foggy days = Game Over if rescue attempt is a bust
-Healing is rather expensive 0_0 ->Instead of healing at the entrance you now have to pay a hefty sum to a fox who only heals SP for you. On a positive note you get more time to screw around so you can ignore the fox and leave to fight another day.
Overall:---------------------------------------------------------------
I haven't quite finished the game yet, but it has been very enjoyable thus far.
