Completed..
Total Completion: 98% 
banghead: don't know where is 2% left coz I have done all (100%) challenges/relics/docs/weapons etc still)
Graphics is amazing...can compete with Uncharted..Lara looks superb (exceptional detailing) and she does reacts to environment very well(when passing through sand waves,water waves or quickly hiding when enemy is nearby)..
water is so much detailed be it muddy green,clean water or pool of blood.
Fire effects are wow...after FarCry 2 & 3 this game has excellent fire details(fire particles) and Lara automatically lights a fire when place is too dark.Cave/Ruins are well designed...passing thru narrow areas is nice...also the human skulls inside caves are so well designed(not just some ignored textures)
Initially before the plane crash Lara is all cleaned but after that for the whole game she is covered with mud and the mud detailing in her whole body is well detailed...the initial scene of Lara is CGI graphics (just like Final Fantasy VIII).
Story is quite OK and not exceptional (u'll agree on this if u complete the game so don't wanna spoil the story).
Lighting effects/rain/thunderstorms/moon all are excellent...the stages/areas are beautifully created and is a visual treat to watch.
Sound..oh what to say about it..nice....the echo of firing a shotgun in open areas is exactly same as it is in real world (wow),music is inspiring and good.
in this reboot there are two major elements
Lara will FALL,FALL,FALL & FALL (u'll will get this multiple times..she hurts herself badly but that is USP of this as its a survivor game)
and second is BOOM,BOOM,BOOM & BOOM (hell yeah lots of explosions....even dynamites are fired by enemies)
Lara's signature weapon is bow & arrow...and are good to use them (for silent kill though pistol and machine gun also have silencer)
actually its a multi purpose tool(the bow & arrow)
Upgrade list is long and good (and u will upgrade everything to 100% so no worries)..
gameplay mechanics is also marvelous solving puzzles,swinging and mountain climbing are well executed.
puzzle are not hard & tricky...using survival instinct helps a lot.(button Q will be mostly pressed)
Boss fights...there are not ending level boss fight but u will encounter a Final Boss Fight and mini-boss one or two.
TressFX is superb..Lara's hair looks so real with it but let me tell u that TFX will eat up 7~10fps or more...so I disabled it while playing.
Need a High-End Card to play with all Ultra-High settings (may be Titan GPU)
Hunting animals for XP is good survival facto in this game.
and Raiding Tombs for large rewards is bonus feature (Tomb Raider).
Extras include videos/concept art/3D Models...3D models are well made (just like crysis/RE5 and other Capcom Games 3D models)
Stealth is also included..and believe me if u play this game silently u'll see enemies doing various activities just like I saw three (a smoking thug and fellow praying to queen in a hut by bending on its knees
and one was pissing around the corner i can see the flow of it (well detailed))
Square Enix and Eidos has done splendid job with this new Reboot...
this is a must play for all TR fans and deserves a GOTY 2013.
My Rating: 9.5/10
within this time I wud have completed FC3 twice
in my review...i have completed every bit 100% be it relic,docs,treasure maps,weapons,skills....have I missed any 
still confused what is the 2% remaining
