yes
- There are many classes to choose from, each can suit your own needs. Gunner, Lancer, Sword & Shield, etc.
- There are currently free DLC patches each month with several new expeditions, armor, and weapons
- There is local and online multiplayer, so you can hunt with friends
- Customizable panels to suit your own style at the bottom of the screen (panels are things you use to customize your layout, like a map or item section)
- Long campaign
- Huge weapon tree
- Unique bosses
That's all I can think of at the moment
this is one of the weapon trees (for the long sword)
Edit: Oh, how could I forget the Palicoes? From the wiki:
"You can bring one Main and one Sub Palico with you on a Quest. If you want to bring Palicoes with you on a Quest, your first one must be your Main Palico. A second, Sub Palico can be selected from the Palicoes you have recruited. Main Palicoes are created when you first start the game and create your character. They are with you from the very beginning of the story."
They also have several Forte Types to help your hunter during a quest. Fighting, Protection, Support, Healing, Bombing, Stealing, Leadership, Treasure, Launching, and Stamina. I've heard they could also purrform team attacks. Purrtuoso ups your maximum health and stamina. I don't use palicoes often, though, and you'll probably forget about them unless you use them often.
