Sure, you can sell it as long as you have no ripped resources, have right to use everything commercially and such. But before you can sell it you NEED to get a business license even if you'd sell it for only 1$, which if it's as big as you explain, is incredibly underpriced for absolute no reason and would most likely make customers AVOID your game because they'd think there's some reason it is such a low price, already at the start. Also, if you sell it for 1$, and after the cut the people distributing your game will take (8-10% cut!!!) along with the tax, you'll not be left with almost any money at all. Realize that even if you'd cut corners in just about everywhere, you'll still have to pay at least several hundred dollars AND you will have to have the license to sell the game for profit. How little money you make has nothing to do with it, you need to have a permit to sell the product you own and to do that, you have to get a business license and market your game as a product you're selling.
If you say you're not looking for profit and are practically willing to sell for free, why not release it free? You know nothing about the market or about RPG maker games that are commercial if you say games don't sell for more than 1$ when most games I found were over 10$, some even going 20$.
Why do you want to sell the game you've worked really hard on for just 1$? If you don't think it's worth more, then don't sell it.
