I just adored this game, and I'm waiting to play a sequel. It was a beautiful story with beautiful graphics. I was engulfed in this game from the first few minutes. I'd have done without all the thunder, though... The creep factor was unneeded, though worth it.
My first ever Mac/PC game was Angband. My second was Avernum, which I played more than any other game to date, and I'm only referring to the very first game! I've played all of the sequels over and over as well. Spiderweb is my favourite company, and Avernum, my absolute favorite series. If they keep shelling out the games, I'll play them till the day I die.
