I supose I ought to say that provided you don't mind the dated writing and technology (not to mention the escalation of over-the-top weaponry) you might like to try E E "Doc" Smith's Lensman series.
And while it might be hard to find, Brian Stableford wrote a trilogy of novels that might be of interest (
The Days of Glory,
In the Kingdom of the Beasts and
Day of Wrath) The first and second are heavily based on the
Illiad and the
Odyssey respectively. Rather different from his more recent works - but worth a browse if you can track them down.
