This is a fun game. I have hunted small and large game most of my life, so it pleases me to say that this entry in the Cabela's series is a more realistic hunting simulator than some of Cabela's other "hunting" games, which are often arcade shooting galleries with predator "horde" modes. (Ugh!) Fortunately, this game is different than those ridiculous arcade shooters.
I've logged thirty hours of game play so far, unlocked all 4 regions of the game, and finished all of the Pro Hunts, which were pretty interesting, but were bookcased with predictably cheesy cut-scenes. I have collected 17 of the 31 available achievements so far (55%). I'm now just mopping up smaller hunts in each region and all remaining achievements. The achievements in the game are sometimes challenging but definitely obtainable, and I expect to get 100% unless one turns out to be glitched. (I haven't heard of any glitched achievements so far.)
Nevertheless, Caveat Emptor! (Buyer Beware!)
Beware of a game-breaking bug. You will likely lose ALL of your progress at some point deep into the game's campaign. This bug has never been fixed by the developers, and they have since been bought out by another developer, so the game-breaking bug will likely NEVER be fixed. The only thing you can proactively do to mitigate this risk is to backup your save files on a regular basis. If you have your hard drive set to back up every night, you may experience the game-breaking bug but can easily just reload your last save files, and you will be back in the game with (hopefully) only minor progress lost.
I experienced this bug myself just 2 nights ago, after reaching the 4th and final region in the game (Northwest), but recovered easily by restoring backed-up save files with relatively minimal progress lost.
So backup your save files regularly!
Otherwise, sit back and enjoy one of the better hunting sims on the market.
