Mechwarrior is basically a strategic tactical combat sim in which 9 times out of 10 if your paying attention you will find your enemy and have time to think out a plan before the combat begins, Each action you do in the mech is methodical, Action is very much present but, it's the initial tension, Also from Battletech on the SEGA you don't have that one health bar, each individual section is armored Head, Torsos(3 sections) arms and legs with back armor for the torsos.
While the customization in the weapons aspect of AC does compare the Franken Mech term which is swapping your legs for treads doesn't happen in Mechwarrior weapons/Equipment only and to an extent engines and armor and jumpjets.
Simply put for describing how the action is, like comparing Need for Speed to Forza both are racing games but, one rewards skill while the other rewards quick reflexes.
Also to further your question about skill base is yes for the most part how well your able to track a mech to obtain missile lock or lead with a gauss rifle or Autocannon determines if you live or if you die no to mention the heat gauge. There is A LOT to it. Though instead of trying to explain it to you, Head over to Mektek and Download the MTX software they have Mech 4 Mercs on there free of charge. Now I know this is MW:O but, other than trying to talk you to death about it go check it out and play it to get a feel or at least an idea of what to expect.
Leaving original post but, blast it sporky you beat me to it.
