Best thing about this game, imo is that you don't have to restart the level every time something bad happens. When i play these games normally, if an alarm goes of, you restart most of the time, but seems more possible to enjoy the game even with them chasing you
I cannot think of a single stealth based game that you have to restart after an alarm.
I distinctly remember in MGS, Hitman and Splinter Cells games I played, you certainly didn't have to most of the time.
Anyway, gameplay looks very promising. It seems they nailed object interactivity. And there is crowd. (wonder what tech game shares with Assassin's Creed.). I noticed characters appearing/disappearing which is understandable but some of them were floating about the ground which is weird as the ground was pretty much flat.
IGN says "graphics aren't awe-inspiring", I say low resolution trailer looks good (especially lighting) and at least scale is there .
