I quite enjoy NintendoLand. It does have a big flaw though, in that it gives you absolutely zero indication of just how much depth there is to it when you're starting out. Given how much it interrupts you with tutorials that's a real problem. It's all good and well making a game that isn't as shallow as it first appears, but if you forget to actually assure the players of that they're not going to bother!|
There are quite a few of the mini-games that have a lot of content to them, such as Zelda and Metroid. The Ninja Castle one has a bit of meat to it too, but I'm not a big fan as I found personally the bosses to be to much of a jump in difficulty and I'm not good enough at it. Donkey Kong is the single player game I've played most, but there's not all that much to it past it having a few levels. The other games aren't as well featured, but Yoshi's Fruit Cart, Balloon Fight and Octopus Dance are solid enough - Balloon Fight in particular could've been a proper sequel, albeit a downloadable one.
As for the multi-player stuff, the Ghost one is a lot of fun with a few people, especially one you've all learned the ins and outs of it. Mario Chase is similar, though I didn't find it as fun as the Ghost one because you've really got less options as Mario - the Ghost can boost around, cast magic and use vibrations as misdirection. Mario can run and that's about it.
I don't like Animal Crossing though. Collecting the candy wasn't really that fun for me, and controlling 2 guards was more than my fragile mind can take The F-Zero one is alright for a quick go but I always find myself going back to the really good games.
