Before he inquires, here's a list of things that are definitely bad about Yoshi's Island DS:
-Ugly graphics, right down to little things like the boss' Windows Movie Maker fade-out.
-Ugly sound, especially that snore-inducing castle theme.
-Lazy, unimaginative new enemy designs.
-Pointless new mechanics such as:
o) Multiple characters, each of which has an ability you use considerably less than the main character (Baby Mario) because his special abilities (running, bouncing eggs) are an integral part of the main game. BP has this same complaint about Super Paper Mario, and he's right.
o) Crappy mini-games that felt like an afterthought.
o) Crappy vehicles that pale compared to the transformations.
-Stupidly easy to beat, but stupidly difficult to attain 100%.
-Only five worlds when six or eight is usually the norm for a Mario game.
-Feeling overall like a retread of the first game but not as good, like a lot of movie sequels. Game sequels are usually supposed to expand on the first game and fix things that didn't work. Guess they couldn't find anything to fix, so they broke it on purpose.
