I was going to work and the outside temperature was about -29C (-20F)... And all I could think of was: This would be great Battlemech-weather. I could easily slap on an extra pulse laser here.
That made me think about MWO: I hope the maps will be diverse, with temperature spanning from "Pluto" to "Hell", because it will force completely different gameplay... provided that heat management still is a highly important issue in this game.
I actually hope that heat management is as deep and complex as it should be. Heatsinks, coolant flush, ambient temperatures, standing in water, exposed to wind, forest fires... All these things should have a tactical effect in the game.
A map should have different temperatures at different places, unlike in MW4 where the entire map is the same. Sun and shade should have different effect, as well as altitude. It will never be the same temperature on a 100 m (300ft) tall hill, as it is in the valley next to it.
And you should have a temperature gauge inside the cockpit that shows you both 'mech AND ambient temperature (or even "effective temperature" if it is windy).
I haven't found anything definite about how this will be handled in MWO, but if I missed it, please tell me

What do you think? How difficult/complex should heat management be in MWO?
