How do I find a trusted retailer to sell my games? Should it cost money to sell my game? What programming API's should I be looking to develop with that will encompass 2D and 3D desktop games? What do I do if I want to go mobile, the API's seem unrefined for beginners?
I know these are a little bit scattered questions, I'm just full of questions, I really want to make games.
How do I find a trusted retailer to sell my games?
Google is your friend, look for reviews, try to contact other people that use the service and ask questions. The internet is a very social place, if a retailer scams someone you will find it very easily. It's very easy to get a bad rep, very hard to get a good rep. Just do your research really, also make sure you protect (copyright) your game before submitting to a retailer you may or may not trust.
Should it cost money to sell my game?
YES! If the vendor / retailer is offering to sell it for free it's a scam. Why would they do work for you for free? Why would they spend their time updating their online catalogs? Why will they waste their money advertising and getting users so they can sell your game and not make anything? Sorry to say it but money makes the world go around and NOTHING is free, there's always a catch. You have to spend money to make money, even if it's commission or royalty based you MUST pay to sell your game. If you don't pay the retailer they will get their money somehow maybe by fudging your sales numbers and keeping a couple copies sales themselves, maybe never giving you a penny. NEVER EVER trust someone that says "Make money for free".
What programming API's should I be looking to develop with that will encompass 2D and 3D desktop games?
This is a much broader topic and the answer is "for what?" If you are looking to reach just windows platforms go with Direct X. Many will tell you Open GL is faster and they are right, unfortunately since Vista windows actively impairs the physical pipeline to the graphics card for anything that is not Direct X. "It's for security". Vista, 7 & 8 will actually make Open GL run slower than Direct X. On every other platform Open GL will be faster.
