Tangent: maybe we should classify FPS by more vectors, such as progression of gunplay (Doom 2016 is a masterpiece there, Titanfall 2 a failure), strength of story (most military-themed FPS are cringe-fests in terms of story), Lore/Tech (Bioshock's Steampunk theme always turned me off, for example), suspense (Prey excels there, COD bores) ... and many more.
This way, we might actually find decent FPS that each of us enjoy based on our tastes. <3
Use "free" Google services so that any pseudo-governmental entity can get full access to your mails, backups, photos, contacts, location ... but worry about stuff in device memory. Yes. A sane approach.
