Naughty dog doing UC4 after masterpiece Last of US, so it will be mostly top quality game like that. Its impossible for ND to screw up and it will be better than Tomb raider. Also you are comparing two different games because UC gameplay and level design, puzzles etc., will be a lot different like Hollywood action movie with realistic and complicated effects unlike Tomb raider semi open world. Did you see UC4 two demos for gameplay ? compare that to Tomb raider and you willl understand that both are different. Also UC4 has multiplayer as extra mode and logevity unlike Tomb raider.
GAMING is not about spending hours to pass/waste our time just for fun,
its a Feeling/Experience about a VIRTUAL WORLD we can never be in real, and realizing some of our dreams (also creating new ones).
So, Feel Emotions, Experience Adventure/Action, Challenge Game, Solve puzzles and Have fun.
PlayStation is about all-round "New experiences" using new IP's to provide great diversity for everyone.
Xbox is always about Online and Shooting.
Nintendo is always about Fun games and milking IP's.
