For me, this hobby has about 5 or 6 "stimulation points" that get me going.
1. The Hunt: Finding that purchase. Checking the usual internet hot spots daily and hoping to find something that catches your eye.
2. The Purchase: Here you have to use your communication and negotiating skills to try and reach a deal. At the same time trying not to get scammed or robbed during the transaction.
3. Transportation of the Beast: Driving home with that 300 pound box of wood. This includes bringing a buddy or one of your kids and having a road trip.
4. Checking out the purchase: The excitement of getting your purchase home and being able to see what you actually have. Is it all original? Has is been hacked to death? Is it working? Any clues to where it has been and surprises left in the cabinet?
5.Fixing/Restoring the game: Here is where you make a plan on what needs to be done and find out if you are talented enough to handle the job. These tests your various skill levels of: Woodworking, electrical, electronic, painting, googling, youtubing, and beer drinking, to name a few.
6. New Purchases: With your new game, you also have an excuse to get some new tools and order buttons, joysticks, cap kits, and art work ect and wait for your packages to arrive.
7. Making the game yours. Finishing all your plans, and getting the game to work and look the way you want too.
8. Enjoyment: From finishing the game and watching friends and family enjoy not only playing the game, but your stories associated from the restore.
I enjoy all of the above when it all goes right!
