Yeah sure trying to make money from games isn't bad or greedy cause sooner or later we will have to make something for living , money is important , thus yeah i think game dev isn't the best way to earn money but at least it's a huge market with many opportunities , and can make a well respected income if you have an extremly acceptable product and a good marketing strategy ofc , cause a good game isn't enough to sell it self , so i think as start for making money from this industry is to start by making mobile games and monetizing them (even tho it wont make that huge income unless you have a very huge audience ) or get a job in a big game studio (and that of course require a big pro experience ..coding,3D modeling,game play programmer,AI...etc).And for itch.io it's not the perfect platform for you if you are seeking a big revenue , but i like it cause it's a good place where indie game dev especially beginners (like me lol) can start their way through to the industry.
