What an incredible game. I'm fairly sure I'm over 40 hours in already since release. Just impressed on every angle and my nitpicks are tiny and sparse. I even like how most of the new monsters are combinations of the old monsters. They feel both new and familiar at the same time. Also, thanks to the reviews and the hype I finally convinced my friends to try out MonHun, and they love it. I haven't had multiplayer this fun with them since the old days of Destiny 1.
Just made it to High Rank before quitting last night, so I got to see a bit of the high rank armors. Can definitely see the grind before my eyes, but I can't wait to get back in there.
In the future, I hope we get more of the series staple monsters back just for the pure fun and fanservice. Also, I dare say I wouldn't mind if underwater battles came back in a DLC, provided they refined the combat a bit. I still like the depth it gave MH3U for monster encounters.
