OTOH I've been told (by CloudFlare support, in contact with their engineers) that for their "for hosting game levels and other content" use case[1], any of their ordinary plans should be fine.
I'm not... super confident in that answer, because despite that being a use case they promote on the site the terms seem a bit murkier, and the page on that use-case doesn't say much about which plan(s) they expect you to use (I'd have expected an "enterprise" plan for serving hundreds of TB of transfer of game-assets per month, but they said no, any normal plan's fine, which... I was up front with them about what our usage would look like, and they held that line, but that seems too good to be true).

I haven't tested these claims yet.
