We should really find him a copy of Civ2 though. All civ players have to experience the High Council at least once!
Yeah, I kind of miss those advisors.
"...else where will our soldiers rest their mighty lances...?"
Er... double entendre, anyone?
Anyway, back to the OP, Kerphunk... I have a hunch that you're improving tiles as the game suggests and not seeing any results from them because perhaps your cities aren't big enough yet. I don't know if it's been mentioned, but a tile has to be within a city's "fat cross" (the 20 tiles surrounding the city in a + pattern) AND worked by one of its citizens in order to yield anything.
It makes no sense to improve a tile long before you'll be able to work it, so although the game says, "build a farm here!", there's probably something more worthwhile your Worker could be doing--such as improving tiles for a different city.
It's also been mentioned that you don't want to focus on some distant goal down the tech tree like nuclear weapons (and I get the impression that very few civ players ever use them anyway). As has also been mentioned, there are other civs out there, run by the Artificial Intelligence, competing with you. If you're relying on accessing some distant, futuristic technology to clobber them with, they'll have you for breakfast. It's more work, but it's better to have a more "contemporary" military advantage--such as Axemen to their Archers, Macemen and Catapults versus their Longbowmen.
This isn't the sort of game where you sit back and let things happen and then BOOM! you win. There are numerous strategic decisions to make along the way, each of them with repercussions both large and small.
Anyway, I sincerely hope you get the hang of the game and enjoy it. Keep us informed as to your progress!
