Now of course what a book like this is really good at is making one want to wargame the conflicts in it... which in this case means the siege of Troy, particularly the "heroic" actions relating to that. It seems like a larger skirmish game would be the way to handle these battles, something that has a hero emphasis like LotR, which happily has pretty much all of the elements needed already, including chariots and rules for mounting/dismounting, which could be applied to the chariots.
As far as I know, there are two sources of miniatures for this period, Wargames Foundry, and Eureka. Both companies have various supporting lines of ancient civilians and allied states that could prove useful as well, particularly if you are more interested in the fantastic aspects of the battle than in the strictly historical.
