I'm really looking forward to Mario 3D World for many reasons. First off, it follows Mario 3D Land in terms of gameplay and 3D Land is like my early childhood Imagination of a 2D Mario platformer brought to life, before Mario 64 was even created. Secondly, the SMB2 roster is the playable hero roster for 3D World! I can't tell you how long I've waited for Peach to be fully playable again! I really want to enjoy seeing her Fire Flower colors! Third, several of my favorite enemies from Super Mario World and power ups will return! The Super Leaf is awesome in the new 3D games! And I missed Chargin' Chuck, the round Goombas, and the Beach Koopas! New Super Mario 2 brought back Reznor! Mario U brought back the Sumo Bros.! I can only hope to see even more things that originated from Super Mario World in the future! And Yoshi! A new Mario 3D game with Yoshies to ride on would be awesome! Plus I found out that at least for right now, the "lose-a-life" jingle will be a remix of Mario 3's version as opposed to the classic jingle for a change! I'm always loving lots of different songs from video games so 3D World is another game I want so I can enjoy the music as well as everything else in it!
But anyway, with the stuff 3D World will already feature, I can't wait to get it!
