I don't think physical media will ever completely die out... it may not be the norm in the future, but it's likely that there will always be a group of people that want a packaged product.
I love box sets, especially when it's clear that there was extra effort put into their packaging. There's just something special about them.
Doesn't Jagex only publish or make free downloadable games?
Easier, cheaper and faster*.
*depends where you live, your Internet connection and so on.
i honestly prefer retail copies of games, specifically ones that aren't tied to things like Steam. the only reason i don't have as many retail copies of games is because of the constant Steam sales that retail stores just won't ever try to compete with.
Just remember that as long as you're buying all your games through Steam or PSN or Origin, you're only one corporate handwave away from losing all your "property" forever. Every person that has installed Steam has agreed to let them ban you from using your legally purchased games at any time, for any reason.
If it has any extra physical goodies I will of course buy a physical copy.
Otherwise it's pointless really.
Why would they do this? How can you pirate a game in-which your computer never touches any of its files.
I love Box Art but digital copies are so much more convenient
