BTW, im impressed that you made your own engine for PS2 and other consoles...
I will say, with positivity and honesty, i'm kinda jealous of your skill.
Thank you for the honesty, and no need for jealousy, what i do, you can do too, you just need to start writing code for whichever console you like the most
if you need help, i have a discord server and i also have books on particular topics and such that can help you out
also what i did to accomplish what i have, was surround myself with very talented programmers and asked them even the dumbest of questions, i have gotten help from a lot of people to get to the point of writing my own games from scratch
