Fallout has been absolutely my favourite game of *all* time. I recommend it to all my friends, and to now have it available like this is a dream come true.
I loved everything about this game; the gritty humor, the storyline, the combat system, but most especially how open-ended your choices could be. Not to mention all the random encounters, and sidequests which really filled out the world and made it much more than the empty, vacuous dungeon crawling and leaf-gathering all too common in today's games.
