The effects of having less water

[Blackhawk748]

My general thought process was going for a cold arid planet. Basically, think a standard Western backdrop, but instead of it being hot, its cold.

Was just curious as to how to do that and I thought "Hey, less water does that" and then I realized there's like a million knock on effects of that. Oon top of the fact that I wanted the water that was available to be in either large lakes or small shallow seas.
