It was quite buggy on release day, but there were official patches and afterwards unofficial ones. With the newest unofficial patch I cannot say I encountered a single bug.
>I lost interest after I reached that big city.
Too bad, at that point the game truly begins and opens up.
>Also, didn't it have that overdone "chosen one" plot?
It starts that way, which I think is a little satire of typical JRPG plots. I do not want to post too many spoilers but I will say that you are not actually the "chosen one".
Also the "main quest" is only one of many plot lines, Arcanum is a pretty open, sandboxy world full of interesting plot lines and characters.
Ehh. Arcanum tried, but its ambitions were pretty high and it didn't really fulfill them. Neat game, but not nearly up to the level of either Fallout title, IMO.
Yes, Arcanum: Of Steamworks and Magick Obscura.
