As it is not being developed by Rockstar I'm hoping it won't have the same awful controls that RDR and previous GTA games have. The first thing I noticed was the compass in the corner, identical to RDR and GTA, so I'm not too hopeful about the controls.
I can't get over the realistic facial expressions on the characters, it looks amazing. I like the crime-solving concept of the game but it looks so similar to GTA/RDR that it's deflated my interest a little bit. I think being able to walk around 1940s L.A. would be cool though, I love the whole look of that period.
