I expect it might be a nightmare. From what I saw playing the beta, it still has many scripted events as if it were a linear shooter and not an open world. If you didn't approach in a very specific manner, certain enemies didn't render at all from more than 150 meters away which is 'no bueno' in a sniper game.
Without intelligent design compensating for the fact that you could literally approach from multiple angles, I expect a lot of frustration from players.
CD Project Red's first open world outting, Witcher 3, saw compromises for this by putting loot in every possible nook and cranny (not to mention a long list of bugs, crashes, etc).
Good luck with a stealthy sniper game from developers that lack crisp writing and technical know-how to compensate. Looking to the history books, any dev team's first open world outting is a gamble.
I liked the crafting / drone play, and the general idea with tracking and so on, so I really hope it turns out all right. I followed many of the dev's replies in forums and I really got a sense that they're learning as they go (at least on the PC side of things), so take that however you like. Good feedback and listening to their fans is a plus as long as its not a design by committee.
If there's enough there, support them with a purchase, so the next one can be even better (not interested in WW2 sniping).
I was part of the beta testing, and yea, there were some simple bugs. I'm not a programmer, so I'm not sure how long they would take to fix. I'm actually really excited for this game. They are leaning heavily on the Farcry theme of open world, base camps, etc, which I like. Playing Mad Max right now, which kinda has the same idea.
I also very rarely buy or play games when they first come out. One, because of the bugs. As Jeff FX says, every game will have bugs when released. And two, I hate the way game developers are releasing games and then added stuff later on. I have no interest in playing a game more than once. I want to play the whole thing when I get started.
