Game Mechanics
Alpha
No more Dieres. If the Corsairs are the fast ones with the triangular sails, that have the white civ color ring I normally associate with barbarians (or maybe it's Cretan "pink"), then I can see them fine when I'm next to them. This is something completely invisible even while Im being attacked or attacking it.
Beta
I just noticed the missing button (Ive been trying to keep an eye on unit abilities). Im curious why you want them eternal, dont really have an opinion without knowing your motivation.
On the subject of Hypaspsists, look at this:

Its veteran, and I didnt name it with the 1st. I did an auto upgrade to Successors. Is this a starting unit you gave a special name to?
Gamma
The Temple of Eshmun does not seem to be functioning as a granary, by the evidence of the city screen (no dividing line in the food box).
Delta
I
always get the named techs in clusters of two, normally on the turn I would expect to complete a tech. The second cant be because of the Library; thats currently being built by the Mauryans in Madurai. The timed techs went screwy on me after being predictable early in the game; at a certain point I received 3 on the same turn. Also I get unexpectedly get an early return on my investment every once in a while:

To tell you the truth, because of the nature of your tech tree I wasnt paying much attention to science/research other than to keep the basic rate close to 8 turns. I havent even built the science improvements this time around, except when I wanted the happy face of an Apollo temple. Consequently I cant tell you accurately when all these events are happening.
If you want Im willing to start a game from scratch and take turn by turn notes focusing on the research rate and the tech tree. Id play that game not towards victory goals, but to experiment for causes and effects relative to tech discoveries.
Game Aesthetics
Epsilon
A spot check for text overruns in the in-game display is probably called for. I think Nubias entry is a little long, for example.
Zeta
Most of the names youve Hellenized already. Id definitely call it Agora. Brings to mind Socrates and Diogenes and all that. Public Space is too generic.
Eta
Speaking of names, how about renaming the Norsemen with something more period and Helleno-centric? Maybe something to connect them with Thule?
Theta
How about Helots instead of slaves? I know it started specifically Spartan, but it did come into more general use, even being adapted in English as an equivalent of serf.
Iota
Also, why Africa instead of Numidia? And is this guys first name Tim by any chance?
