To the City of the Clouds is quite interesting and well written. The archeology genre is not very common, and you'll probably need to be a grad student or professor to get some of the writing and the jokes, but this was generally an easy and enjoyable read.
However, the game's main problem is the rocket-boosted pacing. The game darts from scene to scene, spending little time on each before jumping onto the next. When you finally reach the fabled City of the Clouds, you'll only be spending a few scenes there before you're out.
The game does branch quite a bit, especially given the low wordcount, which might give you an idea of how quickly everything needs to run.
There were also some questions on gender and romantic preferences in the starting chapters, but I don't think I saw much of romance in this game.
If you're the grad student type, or if archeology is your thing, you might enjoy this.
