Today, Spiderweb Software is a daily deal.
These are some of the best old-style, isometric RPG's.
You get the entire Avernum and another series - 10 big games - as well as the first two of the new series, Avadon 1 and 2.
I waited a long time for a big sale and got Avernum for 'only' $75 plus $15 for hint books, for $90 - that was something like 50% off, at least 30%.
Now, all of the above is $7. Really a no brainer if you like that type of game.
One of the series is about a world with 'shapers', creatures they create who are usually slaves, a big bad government, your choices who to side with, and ethics.
