You need to go back and play the original X-wing and TIE Fighter. (Not the Windows 95 ports, the DOS versions.)
Also, possibly Wing Commander 1 & 2 (scored by The Fat Man). But I'm embarrassed to say that I haven't played them yet, despite owning the GOG rereleases.
From the publisher's perspective, the ebook's costs are hardly "negligible", as the retailer gets to skim 30% off the top. Less than a print book (the retailer gets 40-50%), but a decent-sized chunk of change all the same.
"Often none"? How many games work without being signed into Steam? (Hint: that's DRM.)
Among the services that prevent resale and force you to be online to play*, Steam is the least bad of them. Far preferable is something like the Xbox 360, where you don't need to be online or have an account to play, and can let your friends play too.
*Yes, I know Steam nominally has an offline mode. It's been sufficiently unreliable for me that Steam requires online as far as I'm concerned.

The mother didn't. I wouldn't count on the child having them.
