Edgetho: Arcanum seems to be really good. But it seems to be one of those games that are "really good BUT". There isn't one purely positive review in the world (but also no negative one)...
I never said and never will anything bad about the game itself. It amazed me back than and some of the ideas, also from the story, still do till this day. There is no one RPG I like more than "Arcanum" - one of the brightest stars of the gaming universe.
So - I think you can go and risk it. :) Only then you will know whether you like it.
My only complaint was and still is about the engine. Its memory management was quite bad and you had to restart the game every two hours or so to play comfortably. BUT...
I used to have 128 MB of RAM back then. :) When I played it three years ago, it didn't give me such problems.
That's the only real complaint I personally have ever had. :)
Apart from the lack of sequels and disappearance of great game developers - Troika...
