In my understanding, PC gamers are often pretty miffed when a game doesn't have a quicksave/quickload function. It's often seen as an example of "consolization" of certain games (Gamepads just don't have enough buttons for that kind of functionality). There are times as well when a game has felt inconsiderate about the time I spend playing it, deciding that death means playing an entire chapter again to progress with it. It's often compounded if the death felt like it was unearned; owing to buggy gameplay or a failure to understand what I was supposed to be doing at the time.
That said, there are games out there that neglect to include a quicksave function but manage to balance the mechanics of death well, making it feel like dying meant a loss in more ways than simple game progression. Bioshock Infinite, in my opinion, had good enough pacing, solid combat and a good enough respawn system that meant that the absence of a save feature wasn't missed one bit. Death always felt like a result of bad gameplay on my part, I could jump right back into the action and there was a financial loss. Other notable examples were Dead Space 1&2 and The Walking Dead.
That said, with lots of games I'm a pretty compulsive quicksaver. Games like Dishonored and Deus Ex-HR had me mashing F5 about as frequently as the "W" key. Largely because the progression system and arbitrary moral choice systems lend themselves to a specific kind of gameplay; To get the "good" ending and to optimise your leveling you had to be perfectly stealthy and non-lethal, and that meant being discovered and having to kill enemies meant losing out on progession or outcome, forcing you to quickload or missing out. I wish they had similar XP bonuses for killing as they did for being stealthy and nonviolent, awarding XP for swift, precise kills in quick sucession for the same amount as getting through a chapter undetected.
I often replay a game with the intention of not using quicksave, making a game I know well more exciting by having to weigh up risks and deal with consequences. But being the compulsive type that I am I find myself quicksaving anyway, I've even hit F5 during sessions in DayZ if I was going into a significant PvP area!
It was nice to see that among the gameplay options for the new Theif game (although I haven't played it) that there was a chance to disable quicksave altogether, an excellent additon to a stealth game and something I'd like to see included in general.
How about you? Do you use quicksave? Do you think it's a crutch or a worthwhile feature for a game?
