Difference's
 

Whats the difference between all the versions? Is there a good one for someone who is just starting out and one for those who are more advanced? Do some do things others don't? I kinda want to get started on something to eat up some time, but don't even know which Maker to DL.

RPG Maker VX was made for new people. Try it and read all of our crap to understand it better. Make sure to buy it or "buy" it. Whatever you do, just make sure to have fun with it.

Can I "buy" it from your website?

Nope, I'm not part of Enterbrain. You can download it from my site and then when it asks you to buy it will direct you to where you have to buy it.

GLG is right, VX is definatly the best one to learn. If you need any help with anything, feel free to ask. (Too much free time <-- that dude has)
