At the moment of writing, this is the oldest fan mission I've played. Geller's Pride doesn't come with many bells and whistles, but I'd say it's still better than many Thief 1 missions. It just flows better, doesn't last too long, and is a little more intriguing than something like Ramirez's Manor. It has an interesting story hook, and is fun to play due to the somewhat layered approach taken with the mansion you infiltrate.

It really feels like a Thief 1 mission, even moreso than "Shadow Politics", another very Thief 1-esque mission (released much later). It lacks the complexity of said mission, but the simple core is more than good enough!
