For all The Witcher 3 is one hell of an achievement in every regard - until players found out you could tuck and roll to avoid taking increased damage anyway - you'd be happily hunting demons and completing quests in quick succession... only to try and step down a few feet and find Geralt in a heap at the bottom. Honestly, that game's fall damage is ridiculous for such an accomplished hero, and chances are you weren't killed first time by some über-demon baying for blood, but by trying to clear a small flight of stairs in a hurry. Sure, fall damage has its place contextually - not everyone is a super-human capable of surviving massive drops - but when the Halo series removed it in part 2, it was a godsend. Likewise in the Arkham games if you first toppled off the edge of a guard tower or building only to watch Batman flair his cape and come out unscathed - it's pure bliss. What are your tiny, stupid, ridiculous - but essential - things to look out for, try yourself or experiment with in gaming? Let us know in the comments!
