I have to agree with many other players that My Sims Kingdom was probably better than the first My Sims. Cute and fun!
But when My Sims Kingdom came out, with an even higher score from the critics, I decided to choose it between the Original My Sims. I was glad I did, too! Unlike My Sims, My Sims Kingdom has a very clear and interesting plot. You are a "pig herder" in the Kingdom's capital, Capital Island! You have two best friends named Lyndsay and Buddy.
Buddy is King Roland's, the ruler of all the islands, messenger (you might remember him being the bellhop in My Sims), and he brings you and Lyndsay a message that says that King Roland is going to employ a new Wandolier, for the Kingdom is in dire need of help, but most have retired or moved.
So the new part about this is you don't randomly get your "powers" right away, but get to participate in a contest, and whoever has the best skills with their Training Wand wins and becomes the new Wandolier! Of course, the game is programmed to ALWAYS make YOU the winner, so don't worry about that!
Once you become a Wandolier, the King sends you on your first quest: explore the Kingdom and help it's citizens with whatever they need assistance in. And the end, I might give you a reward! So off you go, taking Lyndsay and Buddy with you, on your adventure! Throughout the game, as you travel from island to island, you get delivered new maps by King Roland.
I have finished the entire game, and would be happy to help you with any questions you might have, but I am NOT gonna tell you what the reward is! But it will be "your own"! *hint hint*
Well, it's up to you to find out for yourself what your prize will be, by getting My Sims Kingdom for the Wii. (Don' go for the DS game though, it's boring and badly rated.)
Good luck, Wandoliers, for your quest awaits!
