Okay! So I'm still new to the forums, so I'm sorry if I mention something that has already been mentioned. BUT I do have a few ideas - some simple and obviously possible, and others maybe a little more difficult. Here we gooo.
Quests
So I'm fairly certain that this has been mentioned already, but I would love to see more quests in the game. Even if it's just basic ones... Like having the car and space quests being a regular thing, different magic, scavenger hunt type ones, etc. But I was also thinking something a little different. I remember way back one on the original VMK, that if you visited the Theme Parks, you would be able to do in-park quests. I was thinking there had to be a way to re-create this. Out of the many myVMK users and staff and such, I'm sure there has to be at least one person that has regular or even occasional access to the parks. SO what if said person would go to the park, and come up with different quest questions like how the old ones were set up. Like ride this ride and look for this, or ask a cast member this question and report the answer, etc. etc. This could be done for all the parks in Orlando, or just MK, and the parks in California. You could make a PDF file that we could bring to the parks, either on our phones or on paper, and fill out, and then send in, and get special codes or something that we can redeem in game for prizes.
Re-Releases
Again, I'm not sure if this has been suggested, but it would be an amazing idea if there were some sort of special sales with rarer items that are re-released in stores. Like Halloween costumes, dream items, outfits, etc. It could be like on the myVMK anniversary, original VMK anniversary, Christmas in July, etc. This would be an awesome way to help out newer users start off, or those who missed certain events. I don't think anyone would expect super rare items during this, but just like certain costumes and such.
Different "Realms"
So this would be one of those things I'm not sure would be super possible, but definitely an idea to think of. I know the game is based solely off the original VMK in most cases, and this breaks away from that a little bit. What if there was a way to add different worlds. Kind of how VFK had different sections (colonial, retro, etc.), there could be different sections like Neverland, Hundred Acre Woods, Nightmare Before Christmas, Star Wars, etc. I know it would take a lot of graphic work, but it would give myVMK something new and original, and a little more for people to do - more mini games, quests, store-specific items, etc. Or, on a simpler factor, it would be Disneyland California, and Disney World FL - keeping the original layout based off DL, and then adding a Disney World area - with Epcot, Animal Kingdom, MGM/Hollywood Studios, and MK.
Room Trading
So I know there's a way to trade rooms as pins that haven't yet been used. But I noticed that there isn't, unless I haven't seen how, a way to extract a room you've already used back into pin form, or simply just a way to trade it. This would be a great idea for people to use rooms as they please, and then trade them off when they're tired of them.
