There are only a handful of “legal” ways to get VB6 anymore, the biggest of which is being a student at a college or university that offers it as a free download. But Microsoft no longer sells licences for it and they no longer support it but they also don’t want to to just “steal it”. I think it’s stupid, if they threw it away you should be allowed to have it, “one man’s trash, another’s treasure”. There are plenty of ways to get it, and very few will have you actively pursued. It’s up to you if you get it or not. But it is required to do most of the stuff with Eclipse game engines.
However, Java, VB.net, C++, and many other languages and editors are free or have free versions which you can use to create games with.
http://thenewboston.org/ has many tutorials that will get you started in almost any language you wish and even has some tutorials about basic game programming.
Another great source for leaning about game creation is the RPG Maker series although most of the coding is done for you they all have an open coding engine where you can change or even add features to you games. they also have many tools that would help you learn about design and planing for games.
There are many options for getting into game design and programming the choice of where to start is yours. Have fun and enjoy your digital journey, there are many willing to help you if you ask.
