Depends on the genre, really. Becoming dead after taking a couple bullets works in stealth games, where the combat ineptitude of the player is an incentive to actually use stealth. It works in the modern "realistic action" subgenre of FPSs, where it is one of the two genre-defining features (1. Realistic! 2. Brown!). Survival Horror thrives on it. It might work in some tactical games, like X-COM - Ufo Defense or Jagged Alliance. It works in many, many arcade games (I Wanna Be The Guy, obviously). It works because it's part of that genre. It's why you're playing this game in the first place - and it will not go away on the lower difficulty settings.Treblaine said:I'd like to add that it's not just Stealth games where you aren't supposed to get shot as generally in all games the aim is not to get shot. Flank, snipe, bombard with grenades, shoot them before they shoot you, dodge and move like crazy to avoid getting hit (too much).
Really it isn't a handicap to only be able to survive a couple shots to the body, it's an ADVANTAGE to survive any at all. Or similar grievous wounds.
If applied to any other game, it's jarring. It turns a fun and relaxing game, one you can play for the story/setting/characters/puzzles/environments/humor/graphics/music/whatever, into something of a job. Or a game-long Quick Time Event. Tedious, repetitive, punishing (also, the punishment involves repetition, except more tedious). It's not a gratifying achievement to beat such a game on a high difficulty setting, it's being released from a surprisingly boring nightmare. Not all genres remain fun when an enemy can suddenly destroy you/your vessel/your party/your army with a couple cheap shots the moment you make a mistake. If a boss does it, then maybe you've missed something or it's a That One Boss. Ordinary mook does it? Fake Difficulty.
There are ways of making the game more challenging without killing the player or making him otherwise fail. Puzzles, for instance. Solving a good puzzle is always gratifying. Achievements can be used as an incentive for trying a more challenging playstyle. Painkiller is pretty good in this regard with the Black Tarot card requirements.
P.S. Please note that Towers of Hanoi and Quick Time Events are not, in fact, puzzles.
