Imagine... a STALKER theme crossed with Far Cry 2 DUNIA engine..
Note: No hate towards the X-ray engine, but FC2 has more elements that really could help the atmosphere with visual animation elements like; hand reaches out to open doors/cases/lockers, using your knife to remove a bullet from your leg, seeing your legs/torso when looking down, visual usage of an item (f.ex: medkit/drink/food), hand reaching out when picking up ammo/items/weapons etc..
+ No UI (except health bar when not on full health).
+ PDA's map is an actual item (You can see him holding it while playing.)
+ Huge open world with great graphics and NO stuttering and the smoothness factor is over 9000!!
A man can dream tho'... A man can dream...
