The Yoshi Project: Super Mario World 3

The Yoshi Project: Super Mario World 3 (Known in Japan as Super Mario: The Yoshi Project) is a game in the Mario series. It is a turn from the usual Mario fare of today, as it's relatively deep story and difficulty akin to Super Mario Brothers 3 makes it an attempt to appeal to Mario diehards of the 80s and 90s that have noticed the decline in difficulty from the older games. It uses HD Sprites.

Story
A Yoshi scientist under the name Dr. Yosh E. Gadd started studying the effects of genetically-altered foods on Yoshis. He learned that with various combinations of chemicals, they can give un-heard of super-powers to Yoshis. Bowser then learned about this. He stole the formulas for the genetically-altered foods, and stole group of seven Yoshis, and hypnotized them to do evil, then constantly force-fed them. They then started to attack Dinosaur Land and the Mushroom Kingdom. Evil was prevailing, and there was nobody to stop them except Mario, Luigi, Toad, and Peach.

Playable Characters
Plays like a standard Mario game. Fastest runner. Jumps higher than Mario, is also more slippery. 2nd Lowest jump, but can float in the air.
 * Mario
 * Luigi
 * Peach

Instead of being able to stomp on enemies like the others, due to his light weight, he picks them up and throws them instead, Like Super Mario Brothers 2. Cannot collect powerups, instead gets throwable blocks. Slowest speed, and lowest jump but has 2 bars of health without mushrooms.
 * Toad

Map Screen
Instead of a linear map screen like Super Mario World or any of the Mario games with a map, It has three non-linear hub worlds that operate like Zelda (Dinosaur World,the Mushroom Kingdom, and Star World) with the different worlds within them. The hub worlds also have Mushroom Houses, and rare random events. Switch Palaces are here. The worlds are still to be done in linear order. After each boss, you get an item that unlocks the next world, whatever the item is.

Powerups

 * Mushroom (As seen in all of the main-series Mario games)
 * Fire Flower (As seen in all of the main-series Mario games)
 * Cape Feather (As Seen in Super Mario World)
 * Liquid Bottle (Fills areas with water, and kills fire and ice enemies) (Rare)

Yoshi Powerups
These are only useable by Yoshi, and they only last for a specified amount of seconds.
 * Long Toung Berry (70 Seconds)
 * Cut Berry (120 Seconds)
 * Rainbow Berry (35 Seconds)
 * Sugar Berry (60 Seconds)
 * Infinite Egg Berry (55 Seconds)

Yoshi Riding Gameplay
Instead of using the Yoshi gameplay from Super Mario World or New Super Mario Bros. Wii, it uses a gameplay system more akin to Yoshi's Island. It has the Eggs from Yoshi's Island, with all of the uses for eggs found in that game, as well as the flutter jump. Still, you lose your yoshi, and it runs off if you get hit.
