I like it a lot.
I loved the fantasy of being an Iron Man like dude in a lush sci-fi Monster Hunterish world. This is hard for me to ignore. The art is great, very good taste, I'm surprised more people don't mention it.
The graphics are incredible to me. Don't know if it is because I don't expect the same graphics as the announcement trailers anymore, for any AAA game or it is because I play old games a lot. I played on PC, on high, but I like it even on low. Animations, sound effects, graphic effects, everything is great.
Being a loot-shooter, it is expected the gameplay is not as tight as a Doom, for example. Too many variables and the designers need to make something to be played lots of times. But I found the base gameplay great! Fun weapons to use, good enemy variety and attacks, lots of verticality, flying is important in combat without being cheap.
There aren't enough TPS which are not cover based these days so when the server issues are resolved and I'n positive there is enough content to justify the price, I will get it. If there are too few missions and areas, I will wait for a drop in price unfortunately.
