grappling hooks and guardrails
As I've been immersed in a bevvy of open-world games over the last several months (FAR CRY 6, HALO: INFINITE, FORZA 5, and my "I can't process any other signal hand/eye/thing" fallback, GTAV), I've come to appreciate the sturdiness of the guardrails contained therein: while I can smash through buildings, over any number of obstacles or concrete or trees or shrubberies, those guardrails don't budge, rendering my flights from Covenant strongholds and/or my escapes with Chicharrón after storming the fascistas over before they begin.
Random FAR CRY 6 - HALO: INFINITE thought: the ability to use the grappling hook in HALO: INFINITE on everything ruined me for all other grappling hooks: that I had to search for conveniently-placed grapple-places in FAR CRY was a major let-down but we'll always have Chicharrón.
