Before I start, I should point out that I'm not a "historical purist" concerned with minute historical details by any means, and I loved the "Truth Behind The Myth" approach and CA Sofia's take on the various myths and legends of the time.
The only thing I didn't like was the single-entity heroes and units, and fantastical abilities and splash-attacks. They always felt too much like a MOBA to me, and that's not what got me into the TW games. I was looking forward to Historical Mode solely because of the addition of Bodyguards and the removal or reworking of the abilities to be more grounded or believable, in the hope that the battles would be more focused on tactics and maneuvering rather than who can spam the most abilities the quickest (yes, I'm an Armchair General who likes to feel like a tactical genius when he trounces Normal-difficulty Battle AI. Sue me).
I was really looking forward to Historical Mode, but having spent the last few days playing through an Agamemnon campaign, I have to say, I'm hugely disappointed in the mode. It's a repeat of what happened with 3K's Records Mode; a stripped-down, barebones alternative that plays second-fiddle to the fantasy mode.
In Troy's case, that "stripping-down" somehow seems even more extreme. I was a bit disappointed about the removal of units like the Minotaur and Cyclops (compared to, say, reworking them as small bands of highly-elite units for Historical mode), but I could understand why it was done, and it was a minor gripe of mine at the time. But the complete removal of all mythic units - Harpies, Centaurs, Giants, etc. - completely removes what gave Troy a unique feel and made it stand out for me. The removal of all unique landmarks, buildings, and Epic Agents in the campaign also seems like overkill.
What's even more disappointing is seeing Historical Mode gets nothing other than Generals' Bodyguards to make up for the removal of so much other stuff; it feels to me like trading in 4 or 5 unique features for 1 older one.
At the very least, the addition of some new units unique to Historical Mode would have made it an easier pill to swallow, especially when you see that Mythos Mode got several new units added. Instead, the mode just feels very generic, like I'm playing Medieval 2 with a new skin or something.
While I'm fairly happy with the reworking of Heroes' Skills, I'm seeing more than a few instances (and obvious ones at that) that makes it seem like it was a rush job; ranged heroes are so limited in their bodyguard options that at a certain level, you don't even get two options; other's can still unlock and equip a Chariot Ancillary, even though their bodyguard is composed of all infantry units.
I dunno'... I could go on, but to be honest, my interest just isn't there anymore. There's so much cool stuff and potential in Troy, but try as I might, I just can't bring myself to be excited about it anymore. I've no interest in Mythos Mode - although I'm happy for the folks who wanted that mode - but I was going to buy it just to support the game. But after playing Historical Mode, I feel like Troy - and the Total War series - is going down a route that I just don't find fun.
