I actually played Tomb Raider when it first came out. I obviously was excited to play the newer version of the game, and Lara. I'm amazed at how brilliant the graphics are.
Not only is it far better implemented into the general environment but each zone you travel through has a decent variation in resources and animals to admire/hunt/run from. The only downfall and my biggest gripe is the repetitive reloading of her gun. It really isn't necessary. By the time the gun has reloaded I have already died and then it needs reloading on the next level. Reloading is very slow, it's annoying!
I'll also say, it has more streamlined gameplay, better graphics and performance and more tombs just to name the big ones. It has a really compelling narrative.
