My daughter loves the mini-games on Mario Party. Any other Mario games -- or other games -- that she might like? I can't tell the difference between Mario 64, New Super Mario Bros., Super Princess Peach, Kirby...!
I know this is an old thread, but Mario 64 is an awsome game with loads of mini games unlocked for conquering certains areas. This decision depends on whether your daughter is mechanically inclined. If she is, get Super Mario 64. This game has always been my favorite since I purchased the original/first DS, (fat) and the game has not been surpassed in quality by any Mario related title released to date. At $26.49 as of March 2013 or less for a used version, this is the game to get! (only if you are aware the game can be difficult, and require some good hand eye coordination) If your daughter has these traits, you will not be disappointed nor will she. Should she not have developed these traits yet, an older friend could possibly help in getting past certain areas. It's such a great game, one of Nintendo's classics! you will not regret purchasing the game whether she can currently play through to the end or not as eventually she will be able to play through, and it will be an accomplishment well deserved. This all applies only if your daughter is really into Mario, and completing a story line of sorts where Mario saves Peach, but needs to complete many levels to rescue her. In other words does she have the patience required to play levels over and over until she is able to conquer the level which may unlock more mini games. There are plenty of mini games here, but unless she is interested in actually playing a full out classic Mario game, and not just solitaire type minigames, this may not be for her at this age.
