Amnesia Story

[TGST]

I probably will end up doing that :/
Even though I'd like to do a Let's Play of it.

I head La Caza was really good and long.
I'm not sure if it will ruin Amnesia's story though.

Well, I just checked the La Caza out, and it's not going to spoil the story at all. But, it's going to feel a bit strange to play Amnesia after playing a custom story. The monsters etc. are usually used too much in custom stories, when in Amnesia they are used in a more subtle way. It may ruin the effect of the monsters for the main game/you may act differently in the main game because your first touch to the game was a custom story. The custom story is built differently. But in the end, it really is a choice of yours and yours only whether to play the custom story first or not.
