So nice to see lots of discussion here - as usual, I'll leave the gameplay advice to actual players.
I just built the Great Wall and

... amazing feature on the map, I did not expect this ! (I guess this is from vanilla game?)
Can't take credit for that one! This is vanilla. Funniest when you're on an island and get a 1-2 tile long "not so great wall".
On another note this is the border face-off between Egypt and Ethiopia... another war is looming!
You're missing out on some unit variety by running single-unit graphics. Those shiny shields on the Ptolemaic phalanx among the recent ones I did and I'm quite fond of how they turned out; in this (and many other, though not all) unit, each of the three figures has a different shield design (and usually some other minor details), as pre-modern armies aren't supposed to look too uniform.
Oh no, it looks like my hard drive is kicking the bucket...

I most likely won't be able to play RI for a while, at least while I deliberate on whether or not to make the (probably foolish) choice of fully upgrading my PC to something modern and capable of running any contemporary game without a second thought. Maybe I'll just get something optimized for this though, since I don't see myself getting much into anything else particularly recent or new.
Oh no! I hate it when it happens. By this point, I think I've had half a dozen HDDs die on me, often without any forewarning, and it's always a gut punch. My sympathies.
The flavour of this mod

... just as I was launching my final large scale assault on the Ethiopian kingdom, Aton himself blessed our troops sending a prophet...
That, on the other hand, I (and others who worked on RI), can definitely and proudly take credit for. Literally thousands (close to 2000) splashes for great people.
Hi guys, do you please know if there is a downloadable graphic pack for great general for each of the military eras? I don't like seeing army of fusiliers and grenadiers and cannons led by a dude in chainmail with a sword and shield. Is there a way to upgrade this in RI? Thank you.
I wish! I'd simply take it and incorporate it into RI. It's not that simple unfortunately, as units can only change looks two times - between Classical/Medieval and between Renaissance/Industrial. Changing that
is possible, but is rather involved, with some new dll code, so it's one of those "one day" projects for me.
