IMHO rome 2 suffered from the same problem that civ5 did (for me at least), it simply wasn't as good as the previous. Rome 1 was an epic game and got lots of things right. It didn't need a massive improvement, simply an evolution of "drop the click fests". Empire total was was good but the ranged combat was marmite to most.
Shogun 2 pissed me off simply due to the artificial limiters put on you for expansion (to make up for the shoddy AI) mods did fix a lot of this though.
I'll not bother with warcraft as I have no interest in the warcraft universe.
Its not the cough that carries you off but the coffin they carry you off in.
