I had said the whole thing is a spectrum but with more then 2 points...Honestly, I think something like Combat as Heroes (CaH) and Combat as Anti-Heroes (CaA) is more descriptively accurate of these play styles.
Combat as hero, Combat as Antiheroe and Combat as villian is a great thing
Combat as war and combat as sport and combat as specticul is cool
All 6 of those plus how much you like a challenge all play in...
BUT wait I know someone will say sport v war is the challenge but it really isn't.
Sport can be HARD and War can be EASY.
Combat as the hero can be sport or war or hard or easy... Batman stacks the odds, Superman just walks in and expects to win
