Phew.
For a minute I was thinking you meant the tactic of standing ever so slightly lower down on a hill, so the enemy merc unloaded their M-16..... into their own foot.
Or the tactic of running away, such that the vast mercenary army equipped with VTOLs and Black Hawks decides to call of the search (when you've slaughtered hundreds of them previously, natch) and instead wait to time their attack to occur at the very moment you acquire a rocket launcher or mounted machine gun.
The first never happened to me, but the second... yeah. Like I said, the AI wasn't what was impressive, it was the realism of the game world.
I do like FarCry though. The AI isn't that bad, and, the most important thing of all; it's REALLY fun, imo. Having virtually unlimited ways of taking out the bad guys, while having a game world that acts reasonably like you'd expect it to, is a great boost to gameplay for me. Lots of times I've spent ten minutes just scoping out the enemy, locating their trackers through my binoculars, and spending the next 30 minutes luring them away and taking them out one by one, or flanking the entire camp and destroying them from behind.
Exactly! There was freedom to explore and use the area to your advantage, to decide when and where battle would be met...
