Also, something cool I found out about flashing lights in the distance if you look through your camera in certain places:
I wish they stuck to methods like this instead of everything being in your face. The UI is invasive as it is, but one might also make the mistake of focusing too much on the mini-map. I see so much of Assassin's Creed in this game. I kind wish I saw more Far Cry 2, though I think this game is better in the end.
It is pretty cool, but it doesn't quite nail all the ideas it has. I suggest ignoring most of the side content if you don't enjoy it. I do like liberating camps and while climbing radio towers isn't too exciting, but they are nice to look at. Wish this game had more complicated climbing mechanics (they borrowed a lot from AC, but they didn't borrow this). (I would have liked it if towers slowly fell apart, since they look like they are about to.)
The marking and takedown mechanics seem to be the highlights of the combat system. Mixed with some decent design, this is why I like taking down the camps (though they are starting to prove to be a little too easy even when holding back for some stealth bonuses or testing new weapon types, probably thanks to quite a few upgrades). The silliest thing about the game is probably that you can heal yourself to full with nothing. I suppose that's better than a full on regen system, but I see it as a missed opportunity. With fast travel and ammo being quite plentiful thanks to money, this game doesn't make for much "survival".
Ultimately, it will be the atmosphere which shines brightest. Those caves are especially fantastic. I've been impressed with the main missions so far (on 2nd island now).
There is no way to naturally load a car with C4 and drive it into something right? Kind of a bummer. Spent like 5 minutes trying to get that to work. Tried mines too.
EDIT: The craziest firefight I had was when I seriously tried the flamethrower for the first time (no pun intended). Thought it sucked for awhile. Shit just got completely out of control. It wasn't so much that I conquered the camp's guards, it was more like I out-lived them.
EDIT: Not being able to drag bodies outside specific conditions is a great thing. It makes you commit.
