Niggles: What order would people suggest Spiderweb games be played in?
In order from oldest now free
Exile series then Nethergate, Avernum, Geneforge, Avadon (the shortest series with 3 parts), and Queen's Wish 1.
While you should play individual parts of a series in order, the series are indepentend so if you don't like one skip and play one of the others. You should probably also play the originals first and remakes later:
Exile I: Escape From the Pit, Exile II: Crystal Souls, Exile III: Ruined World, Blades of Exile
Avernum First Trilogy, Blades of Avernum, Avernum Second Trilogy and the remakes Avernum 1: Escape from the Pit, Avernum 2: Crystal Souls and Avernum 3: Ruined World.
Geneforge 1, Mutagen, and 2-5.
Be aware that your actions and decisions have no impact on upcoming parts of a series. If you kill characters in one part, they might still be alive in part 2 or 3. The same holds true for endings: There are one of several but only one considered canonical. If that's something you don't like you had better look for other games. Otherwise hundreds of hours of gameplay will await and you can have tons of fun reading and exploring unique worlds.
