How much plausible is this map from the game Just Cause 2?

[cantab]

The whole region is very small, though that's understandable for game mechanics.

And there are a bunch of apparent rivers connecting two coasts. That's not possible for real rivers. It's physically possible if they're sea inlets, but makes little geographic sense.

[Mateus090985]

Yes, the two "problems" things that I was thinking was "rivers" as you have said and mountains. There are almost no "real" rivers on the map, only divisons beteween pieces of tha main lands. I dont remember if the game put small rivers in the island that are not represented on this big map.
