Long time since I watched some speedruns and I just stumbled upon this relatively new one. No cheating, it's all memory and skills. The guy explains a lot of his strategy and tricks in the comments (GOG is even cited)

The same guy also a did a longer speedrun of Alone In The Dark 2:

Thanks for the link! I've seen speedruns for quite a few games, some of them pretty impressive, unfortunately, some of them use game glitches as a means to do it (which to me, doesn't seem like a 'true' speedrun).

I admire the memory and skill some of these people have to do it, especially with the RPGs (Morrowind's speedrun was pretty impressive), considering I tend to take my time about them.

Neat stuff to watch, but you can get bombarded by spoilers too!

I think using glitches is OK for speed runs. As long as you play the game "as is" and not modded in any way, then everything is fair play. The trick is then to have such an intimate knowledge of the workings of a game to not only be able to beat it, but to do so in innovate (and speedy) ways.

You should see the speedrun of Skyrim beaten in 39:32 :)

Wow, very impressive. I had watched a 1 hour one in the past and was amazed by it, but this one is quite superior. Thanks for sharing. ^_^

In fact, these are not neccesarly glitches but the way the game has been programmed/designed. One of the most possible abused "loophole" is the "nearby respawn" mostly in platformers as the trick is to gain a lot of speed before jumping then you get so far than you're not going to collide with the usual box trigger collider but instead, you're going to hit the next trigger that will respawn you closer to the end of the level. Sorry if that sounds a bit too technical :o)

Another good example of the respawn abuse was in some Dark Souls 2 speedruns when you're character is "out of bound" and then gets respawned further in the game (I think the same trick was used in some Skyrim speedrun).

aye, and even glitches is 'as intended' as this is the state the game has been delivered in, and even though it may be shoddy craftsmanship - it is still created and coded. The point about abusing glitches is still knowing which glitches to abuse and when, as doing it wrong may actually result in taking longer time. The knack of finding the right glitches to use demands quite a good understanding of the game. It looks like cheating when you see a video of it, but there is a lot of background trial and testing before the video is made.
