I like consistent themes in my physical copies. They look nice on the shelf.
Here are some run-of-the-mill DVD keep case releases of pairs of related titles:
North American editions of the last two Prince of Persia games, and European editions of the first two Witcher games.
The 2008 Prince of Persia reboot is nice and DRM-free, like most of its releases. Just the DVD and manual in this package, nothing extra.
The Forgotten Sands has Uplay DRM like in all copies - retail or not. You can install the game off the DVD, but to play without resorting to cracks, the key must be added to a Uplay account. A booklet is not included, only a digital on-disc manual.
Both The Witcher and The Witcher 2 are the Enhanced editions, including all extra game content. They auto-patch to the latest versions, without requiring any online registration. Additionally, you can use the keys to add 'backup' digital copies to a GOG account, for free. This only works once per key, though.
These particular releases are late-ish prints, and are missing all the extra content that the earlier bundles enjoyed (soundtracks, bonus DVDs, printed guides). Basic manuals are included, though. The first game is a combined MAC/PC DVD, the second one is PC only.
