No, it really doesn't look very last gen at all. It just isn't the most graphically intensive next gen game, but there's nothing wrong with that. Titanfall looks quite good for a source title, a lot better than any source title I've ever seen. I think the geometry, art, particle effects and physics all look fairly solid. Titanfall is far from an ugly game.
That aside, we've been prepared for a while now that it possibly won't be 1080p, which I don't really have an issue with, because getting the performance right is important. I just hope it isn't a jag fest. That'd really detract from what I think is an otherwise pretty attractive looking game. Plus, it's a multiplayer title. I don't need the most mindblowing visuals. If I want to have my mind blown, I'll put in Ryse. Titanfall I expect will be a pretty solid release all around, and the leaked footage as of late has made me a whole lot more excited.
I think he is.
