No problem. Like I said, there are probably a lot of people that would disagree with me, but 5e seems to make the most logical sense to me. Once you understand the very core concepts, you can more or less figure everything out from there. There's a lot of niche rules, but if you are just making your own game based on 5e, you can decide what you like and don't like.

Oh hey, I want to message you again in case you did not know. Most, if not all, of the DnD handbooks can be found very easily for free online. The physical books, if bought new, are very expensive, especially if you are not interested in actually playing the game. But all of the rules and information you need, you can search and find very easy.
