Theres actually 35 or 36 legendary pokemons (depending on whether you consider rotom a legendary pokemon. the list of legendary pokemons are: Articuno, Zapdos, Moltres,Mewtwo,Mew, Raikou, Entei, Suicune, Ho-oh, Lugia,Celebi, Regirock, Regice. Registeel, Latias, Latios, Kyogre, Groudon, Rayquaza, Jirachi, Deoxys, Uxie, Azelf, Mesprit, Rotom, Cressilia, Darkrai, Shaymin, Palkia, Dialga, Giratina, Manaphy, Phione, Heatran, Regigigas, and finally Arceus. These are the list of approved legendary pokemon (Rotom is considered by some people to not be considered a legendary pokemon so that is why I said 35 or 36)
There were a total of 96 levels in Super Mario World. That includes special stages, etc. Basically, when you get the little star by your save saying you've 100%'ed it, there's a 96 there. I did it countless times as a bored youth.
@ViolentLee - Several of the levels had TWO seperate ways of beating them, creating new routes - each star on the main screen indicates a 'level completion', not necessarily an actual level. Each of the Star Road levels are perfect examples - beating them at the goal will send you back on your path to the last level, while finding the key will progress on. I think Brett is correct on this one.
When I got to 76 and saw no Interstate there, I was kind of gloomy... then I saw Interstate at 82, and all was well.
I believe this was the best Battle Cars genre game ever. Well done, highly customizable, unlike the "TPS on cars" like Twisted Metal and the like. Good memories of these faceless bastards (literally, they had no face back then, only polygonal heads with some features, none of it part of a face, although it had the odd mustache or dark glasses.)
