I was playing the new Risk on Steam and had one main complaint with it (besides how slow it was). It was the exact same UI for the phone put on a laptop screen. The issue I have with this is that when playing a game on the phone, your fingers can move to any part of the screen quite quickly. However, when playing on the computer, I have to move my mouse to get anywhere. This gets quite tiring when you are moving all around the screen to hit different buttons. There need to be both clear keyboard shortcuts and a UI that is focused on a PC user. A perfect example of something that works on a phone that doesn't work on a PC is the slider for the number of troops to move or place. The very concept of swiping does not exist on a PC but is perfect for a phone. This could be changed to a slider and manual number input.
