If you have been an RPG gamer for at least a 5 years and/or you followed Capcom on Twitter for that time. You have probably heard about the Monster Hunter franchise a long time before their latest installment Monster Hunter World (MHW) came out. Stick with me. I will share with you the perspective of a new player of the franchise.
Personally, MHW was not the first game of the franchise I actually tried. The first game I tried was Monster Hunter Tri (The enhanced 3DS version) and MH4 shortly after. To be 100% honest... I dropped both games like a greasy-hot skillet. I actually has to push myself to try both games just for a couple hours.
If that was at all your experience, hear me out. Monster Hunter World is different than anything the monster hunter franchise has made before and in my opinion it is a fantastic action RPG.
TL;DR Go buy the game if you can afford it. It's a good game and the community is cool.
