Yeah, Shogun 2 is much better than Empire.
Its my 3rd favorite, after Medieval 2 and Fall of the Samurai. Fall of the Samurai is weird in that it uses the Shogun 2 launcher, client, engine and mechanics, but its a stand alone game.
Total Warhammer is 4th. I like it, and I'm a sucker for Warhammer (especially after GW killed the Old World and effectively invalidated my army. Seraphon are not Lizardmen, I don't fucking care what they say), but there's some annoying bullshit in that game.
I used to play Rome a lot, but I got bored with it. The further you go East the more tedious the game gets, because everything feels so far apart. I just couldn't finish playing the Selucids. They feel like shitty Egyptians. And Egypt was boring. I think its because of the Phalanxes, which is the most braindead unit in the game. If you get enough of them you can make an unchargeable wall of death and all you have to do is march forward. Which is dumb. Changing the difficulty doesn't really help, as then you'd get stupid crap like peasants breaking urban cohorts in combat.
I guess that's 5th place then.
I keep thinking about going back to Empire, and every time I'm like "eh...maybe after I play something else"
I haven't played Rome 2, Kingdoms of Britannia or Attila. Well, I did play Rome 2 when it was on a free Weekend, and I immediately thought it was shit. I remember thinking "they went from Shogun 2 to this? What the fuck happened?!"
I initially thought that Attila was just an add on for Rome 2, but apparently its a different game that's better? I don't know, it came out not too long after Rome 2.
Kingdoms of Brittannia is apparently a disappointment, and I don't want to spend the time or money to find out.
