YMMV: Total War Rome II
Hype Backlash: While reviews have for the most part been favorable (currently ranking 76% on Metacritic), the sheer anticipation and buildup leading up to the game's release have undoubtedly caused this among some, with criticisms aimed mainly at the AI and pacing issues. That said, the developers and fandom at large seemed to have handled this well, with the notable exception of TWCenter. It's reached the point that Creative Assembly actually apologized for how the game fell short of both the developers and fans' expectations.
It's Easy, so It Sucks: Longtime fans have complained that the game is "dumbed down for the casuals" due to things like the flag capture mode and the lack of a family tree.
It's Hard, so It Sucks: On the other hand, one of the few less than positive professional reviews complained it was inaccessible to casual audiences.
Loads and Loads of Loading: One of the largest complaints about the game is due to the rather long time it takes when cycling through a turn. This is probably due in large part to the Loads and Loads of Factions that exist in this game, far in excess of any previous Total War game. Patch 2 speeds this up quite a bit, especially early on.
Love It or Hate It: The game seems to be rapidly becoming this. Depending on who you ask, it's either a nicely done if flawed entry into the Total War series or a horrible bug-ridden letdown, with completely no middle ground allowed. It's quite important when you catch up with the game - right after the release it really was a horrible bug-ridden letdown. Patches fixed most of the issues, so if you start playing after their release, the game is just fine. It also depends on the forums: mention it on TWCenter and you got an 10-page Flame Warat minimum.
Silanus, who rises to Proconsul during the course of the Prologue campaign. After conquering the Samnite capital, and with one of Rome's two consuls is already dead at Capua, Silanus then kills the remaining consul in order to pave the way for his own rise to power.
Ditto Arminius, your antagonist in the Teutoburg Forest historical battle and the one AI commander you cannot flatout defeat in the game (even if that's partially from not playing fair on a meta level).
"The men are wavering." Not to mention that it's always preceded by said unit saying something like "By your command!" or "Forever loyal!" before running away like a bunch of silly ninnies.
The constant grunting and shouting of Champions.
Rescued from the Scrappy Heap: The Realm Divide Scripted Event introduced in Shogun 2 as the endgame event has been tweaked into a much less penalizing Civil War mechanic. Gain enough notability in your faction type, and the others of your type (Greek state, Hellenistic, Roman) will gang up on you, but no diplomatic penalties will be inflicted with other factions.
Scrappy Mechanic: Right after release, the flag-capturing mechanic in field battles proved to be incredibly unpopular, with many players claiming it ruined the tactical depth of battles.
The aforementioned Civil War also has its detractors, as multiple fully sized advanced armies are spawned in wherever the Civil War begins, usually your capital. Depending on how late in the campaign it happens, this can go up to 15 armies and fleets ready to ravage your core provinces.
The family tree has been replaced with a senate system, listing only the surviving adult males of your own faction (either the family you chose as Rome or Carthage, or the royal bloodline, or the Elder Chiefs for barbarian factions), and those of the other families. Although a family tree's not quite as relevant in Rome II as it was for Rome and Medieval II, the change is a major overhaul which takes a while to get used to. Plus, it was really useful to see how many potential generals or marriageable family members you had at your disposal, while the current system feels rather random.
Tough Act to Follow: Tied to Hype Backlash above. While the game clearly aims for greatness, in its present state it falls short of what Total War Shogun 2 (or for it's fandom, the original Rome) achieved. It's not helping that the game was initially hyped by Creative Assembly and being made for years with massive budget, leading to over-the-top expectations from players.
