Real - a camper/hearse to convert. Or a workshop
Unreal - a time machine

A roof for my local VFW. The funds are tight and it will need to be replaced soon.

Land

The winning lottery I could start my own company for rpg designing.

Since you guys insist a tiny island a quarter mile square, Beach all around it, some palm trees, a hut. A local woman that could harpoon fish. No tourist.

Breakfast for everyone.

I may have said this...I'll say it again.... TIME

Well, the one wish I have right now is for a fun and well-matched life partner, but that's not a "thing" and I can't "buy" her. If I wanted things or still needed them I could buy whatever I wanted... but it seems I already have 3 of everything I need and 5 of what I don't. The best items on the list below seem to also be things you can't buy... time, hair, health. The trip around the world would be nice, but only with the right partner. Sigh...

UPDATE UPDATE UPDATE

I responded to this by saying I would buy a new roof on August 2 of last year. In December, an extremely generous family member gifted me enough to do that and then some. Just before the new year, during the week between Christmas, I was able to hire a good friend of mine to put a new roof on my modest home. So that gift helped me get that roof and provide work for my buddy during a slow holiday season.

Has anyone else been able to buy the thing mentioned?
