Well, some love it, some hate it.
Some love chess, some like checkers.
Not going to argue with that
Every time you are near a shop, get a new shiny set of gear.
IF you have bothered collecting those diamonds that are f-ing annoying to find.
The main missions wont allow you to keep buying new weapons at all.
That has nothing to do with it.. when you have to spend 30 minutes driving between each mission, you get fucking pissed when that god damn car breaks down.
Its a quick fix, but its damn annoying after a few times.
The map is actually much too good and high tech.
Cant say that the map in the game was that bad, but saying that it was too good seems a bit far to me.. i want a game to be fun, not a wild goose chase where you just hope you might find where in the jungle that one guy is hiding.
A nice feature that made the game unique and atmospheric.
No, it added nothing to the gameplay what so ever as you always had those medicines to take.. it was just really, REALLY annoying.
It could have been a really cool feature to make the gameplay experience more alive, but in reality, it was just a really bad animation creeping on to the screen, that was fixed by the press of a button(And long annoying shitty and repetitive side-missions to aquire the pills.).
It was a game that had huge potential to be something new and creative, but it ended up being a buggy messy piece of shit game where enemies could take a whole mag or even a sniper shot in the head without dying(And no, i dont have bad aim.).
Oh, and lets not forget how repetitive it was! It was so clear that every single mission was based on a set of templates(Bad ones at that.).
But in the end, you are entitled to your opinion, but those "gameplay elements" you listed as innovative, actually had no affect to the player at all(Other then a slight annoyance.).
