Lets just say games aren’t the only thing that’s dependent on the graphics driver. Even Windows UX itself will instead use CPU acceleration when a GPU is not available, and that makes everything choppy, uses too much battery, gets warm, etc.
Not to mention some features like HDMI audio are not available, and that may become a problem if you have a docking station.
Either way, I think we should have a recovery partition of some sort by default. The reasoning is just like the F-keys discussion: People who dont need the recovery partition know how to remove them and the exact implication of doing so, but people who do need the recovery partition are probably less tech-knowledgeable, and may sooner or later come into a point where s/he needs the recovery partition. I mean, making a recovery partition image takes one day max anyway.
PS: There are many ways to install a game without an internet connection, depending on the game itself, but I dont want to turn this discussion into off topic
