well, i thought the idea was original, but after some thought, i realized there were some similarities out there        i want to refine the ideas a little more            ive never done a game before, and I dont even know programming or art programs          im just a newb!      the one thing i dont want to do is pitch an idea without being able to follow through :)

Ok, so here is the short and to the point version.
As a kid I had great fun with mostly just my imagination.  I lived in my own little world. ;)  Most often, I was an explorer, a spy, or a martial artist/soldier. The broken riding lawnmower in the back yard was at times a spaceship, a speedboat, or even a tank.  I just used my imagination!  Another example, the dirt hills by the pond.  They could be snowy mountains, sand dunes, the amazon, or even another planet.  I had the great fortune of having playgrounds and parks close by as well.  I had tons of fun whether with friends or just by myself.  So on to the game idea...
(None of this is canon.  Just meant to show an idea)
The general idea: In real life there is a park, but everything is affected by your imagination!  As you choose which character to be, the scenery and real life objects around you conform.  To finish the game you will have to explore the park in each new imaginary world.

Ok, your the new kid on the block.  You've just moved into the neighborhhood, but you've got a whole summer ahead of you!  To make it even better... You're backyard is adjacent to the neighborhood playground!  Three sides of this open playland are fenced by houses, and from your treehouse you've got a great view of it all.  Summer is here, so let's meet some possible neighbours...
Susie: She is convinced a fortune can be made with just a lemonade stand. Potions, medical supplies, and anything health related can be obtained from her.
Peter: A bookworm of extreme proportions, he even has his own library room. Fortunately, he reads comics too.  He is your intel, lore, and strategic specialist. 
Angelica: This girl lives for dress-up, and her mother used to manage the wardrobe/costumes for a theatre.   If you need armor, tactical gear, or even a diving suit, she is the one to see.
Joe: This is the kid that your mother warned you about.  He spends his spare time carving arrows out of sticks, making potato guns, setting off fireworks, and playing with matches.  If it is a weapon, he can get it for you!
Robert: His dad built most of houses around, and Robert has a knack for making things as well.  He can provide just about any tool or gadget imaginable.

Well, perhaps there is some interest for this type of game then.  :)   Seems like others have had this kind of idea as well.

At the moment I'm just posting the idea for feedback and so that I don't forget!  I will have to post some more of the ideas for it later today.
