If I don't get bored I play very quick games - few hours and all are dead!
But I prefer small maps.
And I found a "strange" thing - if you are super-advanced you better have some 2-3 cities and then you might get more than 1 advance per turn.
It is a pity that even if you get science enough for 2 ads you get only 1 per turn...
I always "show them who I am".
KILL! BURN! DESTROY!
And... CHEAT (politically).
I love getting the Great Wall and then "sucking" their money or advances by demanding tribute every turn.
I think that the Wall and the Library (both Great

) are the supreme Wonders.
Also I always rush for Monarchy and then for Republic.
BTW the pros of Democracy are deminished in Civ2...
And the Wonder letting you any goverment should be MUCH EARLIER than already getting Democracy...
In Civ1 you can get Democracy very quickly and here you must research it to get a "wonder".
Do you think I ever used Communism or Fundamentalism???
I always go for advances and not for superb power.
BTW having some 5 units more than anybody else doesn't guarrantee your victory.
But having an Armor against 10 Legions DOES that.
Oh yeah - the F(O)CC is the best strategy ever!
You build a super city and THEN you get all OTHERS easily!
Pfeeeew - long post isn't it???
