i was about to write fallout 3, but i dint really replay it, i did play it several times but all on the same save, i discovered all places got all the special items and such, but i never made a new char to play all the missions again but eviler.
a game i did play several times was magnus og myggen, a danish click n point adventure game, partly because that was back when i was young and naive and partly because it was the only game i owned, but mostly because of the writing, it was fun and charming and today i still think its a great game.
as of horror games im sorry but i cant help you, i am easily frighted and i hate it, so the idea of paying for a professional horror experience doesn't appeal to me, especially since i will shit my self if a pigeon looks at me funny.
