Hello there! Have no fear, age matters less than your ability to create :) I take my hat off to you sir, I am envious that you create your own tabletop systems! I have DMed a few Dungeons and Dragons games and couldn't get by without the rulebook. I tend to take inspiration from them whenever doing an online tabletop roleplay, too. Alas, I don't have the ability to work out the mathematic/scaling side of things well. I do enjoy flinging people into unexpected situations, however :) Oh! and I tend to argue with DMs that think its their job to kill off their players and give 'em hell. I think it's more in creating a world that breathes and giving them challenges. The killing-hell part is an enjoyable bonus.

I'm a big fan of Ghibli movies, I really like how creative the worlds are. It'd be hard to pick a favourite out of all of them... perhaps Princess Mononoke comes a close first. 

Nice to meet you too! Hope this forray into this forum is enjoyable for the both of us :)
