Well, you do have FOREVER to finish the quest, you just missed the time limited prize
Every building will cost more and more and more, it depends on how many buildings/houses/stores/places you already have
The few places I have not yet unlocked cost 2 000 000
Why not take a break from quests and do events, collect money, or whatever you want?
This is not a race to finish first
Take your time - I'm on a 2 year break from quests (I'm not sure I want my sims to die), I'm just doing events until I know if I want them to age and die - I know there are places that I can't unlock without the orbs but there are still plenty to do
A tip is to read the quests before you start, how long it takes, what is the time limited prize (and do you want it) how many sims are needed when etc
The Girl Who Games is fantastic, I do recommend her blog, I linked the quests but she also have the info on events
Starting over would be more frustrating (at least to me)
I have 20 Hobbies that are completed and starting over means I have to level up all of them again
I have 2 professional workplaces leveld up to 100%, I don't want to do that again - it was a grind to get them to 100%
I like the Sims I've made, the event prizes I've earned - all the time limited stuff from events, promoes etc would be gone, possible forever
Starting over would not be for me, I would loose too much that I could not get back and had to toil to get back some of it
but this is your game and you do whatever you want
