I've been intrigued by aquatic dinosaurs since I was a child, so Time Machine was a no-brainer pick up for me. Played for about a half hour last night and had a lot of fun.
The biggest negative is that the graphics leave a lot to be desired. When not in motion the jaggies on screen are so bad, I almost feel like I'm back in the PS1 days. It's not so bad when moving as there seems to be some anti-aliasing applied. This is for the scenes around the base, underwater things look better, but the graphics never really rise above PS2.5 level. The other thing that bothered me is that I encountered several instances where the screen is black, with no sound, for several seconds. These are purposeful loading times, but it seems like something could be shown in these instances.
On the other hand, even with the below par graphics, the sense of presence is great. Maneuvering around these giant creatures underwater was awesome and sometimes terrifying. I also had fun flying around the grounds of the base and examining all the structures. And when the first real time travel sequence kicked in and the clouds in the sky started zipping by at great speed, I had a big grin on my face imaging myself as Rod Taylor.
Looking forward to playing more, but Skyrim Remastered has been cutting into my PSVR playing time quite a bit (I would give my left nut for PSVR Skyrim).
