Stealth Fighters useless?
I always use them to scout out enemy territories before bombarding, how else should i know what the hell im aiming at?
About Mobile SAMs; the ai once sent 9 bombers on my city with three sams in it and if i recall correctly they downed four of them(at least three), its seems to me they can down multiple units instead of fighter one-shot. And about fighters, i belive that a failed AS roll results in a fighter not even engaging enemy aircraft AND loses ability to intercept next bomber.
Guerrilas i regarded as useless for a long time, but ive found they can be quite useful.
1.The passive bombardment = support for infantries.
2.Same attack rating as inf. and cavalry.
Artillery is normally used as support behind inf, but they can be bulky with their vulnerability and you really dont want them captured ore destroyed.
Helis is for dropping infantry on enemy resources to pillage them.
Cruise missile finish damaged units, they are mobile in your territory unlike bombers AND have better range than infanty.
Finally, some points on knights.
1. Researching chivalry is a waste of research, i always go for theology for sistine chapel and further to education for universities, you can always trade for feudalism.
2. Knights are to expansive, in really pressed situations you dont have any use for the 2 move, pikemen/longbowmen for defense is much more effective wilsts using MDI/longbowmen for offense
