Thanks for all the replies.
I am going to try gold strangulation, although I think it will be tough. I have done a bit of that, inadvertantly, with Hades v Ra on a River Nile map and it worked. By inadvertantly, I mean, I just went over, found the gold, took over some villagers and worked the mine: if the other side hadn't mined it, it was mine. I deprived him of 2 gold mines that way and there aren't that many mines on the River Nile map.
Oh X2C_41nT2L82Qu1T, you asked whether when I rushed Ra he countered me with elephants. No, he doesn't, but, if I don't rush him, he builds up to the point where he can use elephants and I find them tough to counter. I tried playing a River Nile set up with Loki v Ra instead of Hades v Ra, because I had been successful as Hades, but, even though I had full naval superiority, and the other side couldn't even touch my resources or buildings, I still couldn't beat him once he got elephants. I found the Egyptian buildings to be tougher than other types of buildings as well.
I was playing on moderate difficulty if that makes any difference.
As for Loki being a weak god, I disagree. Sure, you don't get the dwarven mine like you do with Thor and sure, the humans don't regenerate like they do with Odin, but, on the other hand, heroes can summon myth units *on their own* in combat and I find this very useful. It hasn't worked as well with the Egyptians, but it worked a treat when I pitted Loki against Poseidon. Also, the Spy power is very helpful: put it on one of the oppostion's villagers and you get at least some idea of what your enemy is doing all the time.
Anyway, I'll give gold starvation a try and I'll also train up fire giants. Fire giants are very cool, aren't they?
Thanks again,
