Arcanum is indeed a great RPG, and one of the few RPGs where being evil is actually feasible. There's just something cool about trying to persuade someone to give you information, failing horribly, and then killing the person, conjuring his spirit, and get the information you need without trouble. Oh, and tell him how you're going to use that information to kill everyone he held dear in life...
Sacrifice is also a very underrated game. In my opinion it's the greatest RTS of all time, with its fantastic(then) graphics, and it's unique playstyle of casting obscenely powerful spells, summoning and commanding weird creatures, and gather souls. Nothing gets your adrenaline kicking like Sacrifice, which is usually not typical of an RTS.
Also, FAHRENHEIT is a recently released game, but I doesn't appear to have sold that well, and few people seem to know it. It's an adventure game, but it doesn't restrict you the way adventure games usually do. You have to make a lot of moral decisions, sometimes very quickly, and your decisions affect the game rather drastically as you go. It's really an interesting, and very different experience, compared to more conventional games.
