I haven't played the game enough to know which is better. Command-click certainly seems acceptable.
Given that right-click doesn't seem heavily used in the game, another approach would be to create an alternative to right-click every time it would be used. E.g., instead of right-clicking on an enemy maybe you could click-drag to a "display" symbol to bring up its info. The advantage of that would be that it would also work on tablets, etc.
