MHW has been garnering a lot of praise, and rightfully so. It's fun, it's huge, plenty to do, and many reviews have mentioned its friendliness to newcomers.
As a newcomer myself, that last bit was important to me, and if you're new to the series, this is a great time to begin your monster hunting... with a caveat.
One needs to be fully aware of a couple of things before taking the dive.
1) it may be friendly to newcomers, but it IS an in-depth game that has a simple premise, but requires a lot of experimenting and learning from mistakes. Friendly it is, but forgiving it is not.
2) this is not a game to pop in for short bursts. It requires time when you load it up. Hunts can eat up 45 minutes, only for bad luck (close to a kill when a roaming monster stronger than the one you're hunting suddenly stumbles upon your epic battle,) to intrude and you need to begin anew.
If you enjoy "Souls" style games, MHW will be somewhat reminiscent. You'll learn from mistakes in battle or realize you chose to carry the wrong weapon for this hunt, OR realize after several attempts that you need to level your gear some and have to halt the hunt altogether while you take on sidequests to earn gear upgrade points.
MHW may feature a lot of action roleplaying fundamentals, but beneath it all is a tight tactical simulation that requires you to memorize your prey's attacks and when they'll use them, what PART of the body is weakest on them, and to save it all to memory so that if you fall, you'll return to the hunt a better hunter.
The creatures and gameworld are gorgeous- one of the few games I wish I had a PS4Pro and HDR to see it even further in depth.
But, the beauty goes beyond graphics. There's a level of immersion involved thanks to not just seeing creatures of different types interact in the wild as you explore, but even to the loot system.
Looting makes sense, in a BIG way. You can, on many creatures even cut off their tail. But, if you need a creature's tooth for an upgrade, attacking it's head to "loosen" it up will increase your odds.
Fighting a creature that breathes fire? Find a creature with natural fire immunity and hunt them until you have the materials you need. Fighting a venomous creature? Odds are those poison arrows are worth about as much as a regular arrow. Fighting a creature who can fly? Attack its wings to prevent it from taking flight.
And much of this common sense approach helps offset the MANY things that MHW WON'T be newcomer-friendly about. If you don't enjoy discovering things that many games consider necessities to teach you, then despite the reviews, it may not be for you... Unless you're willing to search the internet for.
If you have patience, if you're looking for a game and world that will keep you sucked in for untold hours, then you owe it to yourself to take those first steps into Monster Hunter World.
