Steam version is much worse than the fan UI options that were already available, sadly. Its also why I explain why DF really failed to take off after the Steam release. It's nowhere near the best, or even best looking, way to play the game.
I pretty strongly disagree. I can see some preferring some fan art style over the official one, even if I don't. But the official gui having support for rendering all the various critters, and factoring in clothing, multi-level, etc, really made the Steam version's graphics vastly better than anything else that was available at the time.
