If this were math than it could be Phantasy Star + Monster Hunter + Dissidia (JP) combined.
Good:
-Easy controls
-Lots of weapon types to master and characters to level up
-Battle Royal in versus mode
-Thrill of stealing kills with a bow :)
-Epic boss battles
-Great time killer
-Strangely addicting
-Many challenges and bosses
-Good graphics
Good/ Bad
-Easy to level up (too quick makes the game easy but leveling up is always fun in any game)
-Lock on system sometimes make the game too easy
Bad
-Easy game to beat if you have 4 people
-Item trade abuse (trading items and not saving)
-Some objectives are unclear (kill the butterfly)
-Last time I played Dynasty Warriors, you had soldiers on your team
Overall, this hack'n slash game will hook anybody in!
