What geologic features could this video game environment be modeled from, and how do they form? I have been playing this game for a while and I like the city's setting. It seem to be placed on a rock platform, or a mesa maybe, connected to the mainland on the bottom-left. It also has some connection in the top left and middle right.

I would like to know what this structure is called so I can find some real-life such occurrences in order to draw some fan-art for this game.

I would also like to know, if possible, what sort of parameters does nature require to make such an effect. What kind of climate, rock combinations, that sort of thing.
Looking at the landscape, it almost appears to be a highland, with steep valleys carved by a misty river - which suggests possible waterfalls.  I am reminded of Victoria Falls, on the border of Zimbabwe and Zambia (part of the landscape pictured below)

The geological processes that formed these features is summarised in the webpage The Geology of Victoria Falls as a series of tectonic and erosional activity over an ancient basaltic bedrock, forming a series of near parallel gorges (shown below and from the webpage linked before).
