So, maybe the definition of casual games is different for you and me. I don't consider the Mario 3D World and Donkey Kong or the Sonic and Mario at Olympics casual games. Just like I don't consider DK Country Mario 64 and Mario Strikers a casual game.
And most of those games you listed I haven't even heard of. Are they all released?
Yes, they are all released.
2d platformers (and in this case, sm3dland) are casual games, whilst marios like mario 64 are not. This came straight from shiguru miyamotos mouth as well, I will provide a summary first, and then the actual quotes. And this needs to be stated first and foremost, being a casual game is not a declaration of quality, just of game design and purpose.
Its actually pretty obvious, mario 64 is actually NOT a platformer, like a 2d mario is. Its an adventure game. The difference comes in how the game is designed, as succinctly stated by Shiggy himself: 3d mario's like mario 64 are too intimidating, too daunting for casual players to try, mario 64 is an adventure game, when you enter a level, you have to find a star that can be hidden anywhere. In 2d mario, and 3dworld, you go from the beginning of the stage, and head right until you reach the flag pole. Thus, 3dworld is the 'missing link' that will get casuals to play a 3dmario.
Miyamoto: "When we made Super Mario 3D Land, we thoroughly discussed what the definitive difference was with the 2D New Super Mario series4, and what they shared in common. This time, we pushed ahead further with that concept-the concept of making a 3D home console Super Mario game that people who like the New Super Mario games can also enjoy. "
3dworld was specifically targeted at people who would play 2d marios, but not mario 64 style.
Hayashida: "We have worked on 3D Super Mario games the whole time from Super Mario Sunshine2 to Super Mario Galaxy 2. Usually, you would just move Super Mario Galaxy to the Nintendo 3DS system the way it is, but I thought, "Would that really be all right?" So the first thing I said to the team was, "Let's reset." "
They SPECIFICALLY aknowledge they are not trying to appeal to the established userbase for the mario 64 style games. They dont want the 7-10 million 3d mario fans, they want the 20-40 million who will by 2d style marios.
Hayashida: "I live a few stations away from the station nearest from my home to the company's, so at first I thought I should aim for light courses that you could clear in about that time and stop playing whenever you got off the train."
They specifically mention removing the need for player investment from the game.
Iwata "That's a big difference with the Super Mario Galaxy series."
They specifically state this is a big difference compared to games like galaxy/64. They are targeting casual design.
Hayashida "Yes. To me, Super Mario Galaxy 2 is like the Manchu Han Imperial Feast."
The analogy to food is spot on, casual games, with low entry barriers, and no investment/commitment requirements, are very much like small snacks. Casuals can live off of small snacks no problem. Core gamers enjoy snacks, a little candy, some cheese poofs, its good, its fun. But we cannot survive off of snacks, and it is very clear we are starving.
Dont take my word for it.
"It's the kind of game that says, "There's all this laid out before you, so eat whatever you want!" To eat it all takes hours, so when you finish eating, your stomach is full. We put in everything that had built up since Super Mario Sunshine and made Super Mario Galaxy 2 to be a game that has everything."
"Yes. So this time, I wanted to make a compact game that, rather than the Manchu Han Imperial Feast, was lighter, like a hamburger you could just gobble down. I decided to start thinking from there."
This, is the design mindset for casual games. Snacks, you can gobble down, and then leave. There is no investment.
You can play for 10 minutes, have a gaming session, and stop, because you really have no investment to continue. You didnt anything new, nothing interesting has been revewaled, their isnt anything you have to know what happens, there are no permanent power ups for you to investigate on uncharted areas of the world. Ten minutes can be just as good as an hour. There is no investment.
So, lets look at these games.
Mario and sonic at the olympics. Well, its a minigame collection. The very definition of a casual game design. Snack sized gaming bites.
2d mario, you go level by level, beat one level, you are allowed to move to the next spot on the map. One level is just as good as 10, if you stop after just 2 levels you arent going to need to remember where you stopped or where you were going. Snack sized gaming bites.
Mario strikers, a sports game. Played by matches, matches are a few minutes each. Snack sized gaming bites.
Core gamers, people who play zelda, mario, xenoblade, etc, look SPECIFICALLY for that worthwhile mental investment. Nintendo, has been SPECIFICALLY ignoring them. You can tell as much just listening to what they have to say.
Hayashida: "Another task that arose because of Super Mario Galaxy 2 was the divide between fans of 2D Super Mario and fans of 3D Super Mario. "
They KNOW mario 64 style players, and 2d style mario players are NOT the same people.
No, they seriously KNOW, im not putting words in their mouth.
"Yes, there are people who say, "I play 2D Super Mario, but not 3D Super Mario. The reason I suggested including the instructional DVD called Super Mario Galaxy 2 for Beginners3 with Super Mario Galaxy 2 was because the distance was growing between people who were familiar with 3D Super Mario and those who weren't, and many were saying "I can't play those!" before they had even played a 3D Super Mario game. That's really too bad for people like you who have worked so earnestly on Super Mario in 3D."
They Know 3d mario players will play 2d mario, but 2d mario players wont take the time to learn how to play 3d mario. WHat they didnt know was how much abuse those core gamers could take, how long they could starve on gaming snacks, 'junk food' before theyve had enough. Hopefully, they now know. Because the casuals, have been complete no shows. And NOT for lack of quality games targeted at them. They dont CARE about quality, because they dont look for any manner of investment, just something to waste the time.
Nintendo has made it very clear, what they consider casual, and what they consider core games. Core games are feasts, that you play until full. Casual games, are bite sized snacks you can gobble down, and leave at any time.
Nintendo, has made it very clear, that 2d mario, and Mario 3d world and land, of their own purposefull design, are casual games, targeted at the audience who wont buy the wii u. While the people who HAVE bought wii u's, are left starving scavenging scraps of junk food between meals every six months.
