Hard pass for me on this one.
I generally hate it when people whinge that, "This [game X] is just a reskin [of game Y]!". In this case, however, it actually feels like that's the case here. I already own Troy; I'm good.
And of course, that's setting aside all the reasons I've become disenchanted with CA and Total War in the last few years. I could rant, but Gus and
'geek have already covered the main points.
