This just doesn't make any sense, at all. Commercial means someone makes money off of it one way or another.
I'm trying to explain to OP
What makes a commercial game
Is that is A big name Title.
think like this:
If something is commercial
You seen it on a commercial
Because it's made to sell!
sorry if what I wrote confused anyone,
I'm just trying to explain that part.
Because this is where big budget devs actually have to do to actually hand-sell and promote their own entertainment productions is how well they can marchandize.
Let's face it - RTP games alone can be a dud of a hard sale. (The phrase "this won't sell. Cos this won't do." Comes to the mind. Do it right to win.)
However, also to bear in mind that fact.
Yes, it can be considered a commercial success if one sells on their own. Depends on how they revenue after compared to the budget put in out.
But, if it wasn't made for free, then profit has to exceed what you put in to the table (paying for employees, resource, outsource, afterwork drinks.) To be considered not a bust.
((All works of entertainment either comes with a boost engross or a financial loss when it comes to final product output with serious commercial license product.))
Most people that make a game only focus on the dev-work, playability, creaitivity, enjoyability. That's fine.
But pushing for a released product takes a physical barcode with a ISBN number, Expert Reviewed Rating, Translation, Coordination Team including Marketing and P.R. and QA Support, Multi-Packaging, all the extras including copyrights, patenting, trade marks, royalties, product support.
However, the freedom of digital marketing is always the ability to cut the need for physical pressed copies and make the money directly yourself.
However to make a physical copy for valuable collectors item still takes a little bit of capital but worth it to be a commercial success.
