So I got home last night and out something like...3 or 4 hours in when all was said and done. Overall impressions are really positive. Trico is a pretty amazing character all around and I'm blown away by how real he(?) seems.
I also really enjoy how the game kind of discards a lot of the typical...game shit. It expects you to figure a lot of it out on your own and you really have to approach it like you're playing with a real animal.
I definitely had a moment where the game made me check myself. I assumed I knew how to progress, tried to get Trico's help and it just would not happen. Ultimately I found the solution was much more straightforward than I had tried to make it. Felt like a bit of a dingus afterwards, but live and learn. Also I got to a puzzle that I could just not figure out. The bones of it were obvious enough, but I couldn't grasp what the goal ultimately was. As it got later and I got more tired I definitely was not on my game, so I called it for the night. That said, Trico has been mostly cooperative and not at all a point of frustration. All the hang ups I've had so far have been entirely my own doing.
Also the framerate has been good enough on my launch system. Noticed one place where it chugged a bit more but it was brief and not a big deal.
The camera has also been fine more or less. I took people's advice and just cranked the sensitivity all the ways up from the start. It's not like most game cameras, but once you get a feel for it it's perfectly usable.
So again, really enjoying it so far. The world is beautiful, Trico is wonderful and so far the game has been giving me the warm fuzzies. I've been waiting so long for this to come out, it's almost surreal to be experiencing it first hand.
