I can count on one finger the number of sid island games i played out to completion. since sid games are such huge commitment i'm asking this question. when will my fully healed modern armor army get attacked? I'll give some scenarios. assume a sid game invading one of these tough islands. Does my army get attacked or not?
1) I'm at war and I land one army and let it sit there. does it get attacked?
2) Same as (1) except I put a weak non-army unit on the same tile.
3) Same as (1) but I put a weak non-army unit on a different tile that the ai cannot reach because it's blocked by the army.
4) Like (3), but instead of a weak unit that the ai cannot reach it is a new city that the ai cannot reach.
5) I land an army and a settler. I declare war and found a city. My army is on the city. No other units. Will the army be attacked.
6) I found a city and surround it by armies. The ai cannot reach my city. The city is full of artillery. Will the ai be so kind as to at least move its units next to my armies so i can shell them with my artillery and do a bit of leader fishing?
That probably wouldn't work on Regent, let alone a higher difficulty level. (Not that I play on a higher difficulty level)
My strategy to invade an island is pretty simple. Land an army covering a SoD. Then use the army to cover the SoD (complete with artillery) and take or raze all their cities.
That won't work very well above Monarch. On Monarch, I thin I could get away with it.
