1) Reasonable copyright duration. Long enough to give creators a chance to recoup their investment. Short enough to not get in the way of enriching the public domain. For games, something like 5..10 years should do. Books? Maybe a bit longer.

2) For creators: offer your products at a price & in a way such that for the vast majority of (potential) customers, your product is the most attractive. Jack up prices, add draconic DRM, and customers decide that pirates offer the better product. That's on you, not those pirates fault.

Failing that, Nintendo & co loose the moral high ground, and have no right to complain when people break DRM, distribute illegal copies to run on emulators etc.

Or maybe conclude that copyright laws don't serve the public, so maybe it's better to abandon / ignore the concept entirely.
