George is right, it's not a matter of medium. There are loads of artists who have become famous or popular simply by using traditional medium.
There are two problems with becoming a famous (or at the very least more well-known) artist:
1) There are simply just so many people out there. Whether they are good or not doesn't matter in this case, there are just so many it's hard to stand out from a large crowd with similar interests.
2) It's more about social skills and having "connections" rather than actually producing good work. You can be the best artist in the whole world, but if no one knows you (especially people who can create a vast circle of connections), then you're not going to get more people to look at (and maybe even buy) your artwork.
I don't think that's how the artist world should work, but unfortunately it does.
And some artists come across those people with large connections as soon as they start, others after years and years. Maybe even never. This doesn't mean you should stop making artwork. It simply means you should be going on.
I've been busy with the furry fandom for over 5 years, and from that moment on I actually started to become more and more serious about my artwork.
However, I've been drawing my whole life and trying to get people to notice my artwork. Not so I can make a profit, mind you. Ever since I was small (quote: "Ever since she could hold a pencil") I was drawing.
I draw because I want to, because I like it. I focus on that.
And extra benefit to me drawing is I see how it makes other people happy or even fascinated.
That's the second reason I draw: It makes others happy, so that's why I want to share it.
So while I've been drawing furry stuff since 2012, but I was drawing way before that.
Something that started to help is doing free art or art trades with other (more well-known) artists.
It is usually something short-lived: You get a lot of attention, but overall it's short-lived and the interest will die out.
However, you might have the odd one here and there sticking around. Any person who is interested will benefit you to the goal you want to achieve, which is to become more well-known and when you get more well-known, youcan get more free advertisement.
Another thing that might help is making fan-art. With similar results as making free artwork and art trades.
I think you should draw because you want to and because it's fun to you. Whatever medium it is.
Maybe do livestreams when you create your art projects, that also seems to help a bit. Perhaps upload your streams later to YouTube or such.
It may take a lot of effort, time and patience.
Took me 5 years to only get 100-120 watchers on deviantArt, which doesn't sound like a lot, but it started to grow a lot more once I was busy for about 4 years. Just to give you an idea how long it can take with barely any progress, but I still see it as progress.
Anyways, I hope this helps to some regard.
I might be able to play your game next week ;D
