[quote name='jello44']It's basically Pokemon, but instead of fighting with cute furry animals, you fight with demons, and it has a much more engrossing storyline.[/QUOTE]
Wow, no, not even close. The monsters in persona are basically just equipment that your character wears. You can only have one equipped at a time but they can be changed out whenever you want during battle. depending which your character has equipped will determine what spells you can use, the elements your strong against, etc.
There are other Shin Megami Tensei games that are similar to pokemon, but Persona4 is not among them.
