It's not much action-oriented, though. At least that's how I have it in my memory.
I just read about this game Arcanum on GOG.com and like it ! So far I can read this game have many NPC's, quests and a free to explore big world ! I love "technics/technology"(steamwork, yes) and I love Magic ... hmmm ... maybe this game is made for me?
What do you mean saying "not much action-oriented"? Do you mean it have less hack'n'slash? Another question: do you remember this game have some (mind-breaking) puzzles to solve?
