^^ Yeah, pretty much that.

I like to collect certain games/cartridges to satisfy that collector's mindset and also because playing the game on a console is more fun to me that on a computer.

However, if someone can't buy the game new to support the developer, then you're not stealing money from the original creators. All used cartridge money goes to the used game dealers, and that's that. It's the same thing with new old stock. I'm sure there's exceptions, but pretty much all retro games still in the wrapper still see all the money go to the owner of the game. The game was bought new ages ago, that's when the publisher got their money. Now the game is a "new" game sold through the same dealers as all the used games.

I have nothing against used game dealers, but I'm also not going to fault someone who wants to emulate something like Suikoden 2, because they can't afford to pay these types of prices for new and used games.

Although, I think Suikoden 2 is pretty cheap on some virtual consoles now, so it might not be the best example.
