In my opinion they look pretty much alike.

She (the above pic) is the TLoU one just with a lower jaw and paler skin. (Again, my opinion.)

Beyond because TLOU is multiplatform, o shiiiit...

I want a third option: Play B3yond!

I choose Last of Us, because the trailers got me so pumped and I dropped dead when I saw the gameplay demo at E3. I like how Naughty Dog did a very realistic post-apocalyptic situation. With the nature taking over the buildings and everything. Don't see that in many other post-apocalyptic games. I was very impressed by that.

Also, I am familiar with the Ophiocordyceps unilateralis fungus, as ants are a very interesting animal to me (definitely one of my favorite insects), and I've read about this fungus in a few books about insects, and seen it on Planet Earth and other documentaries many times. So I suppose you could say I can relate to it a little bit.

its just the Hair, they dont really look alike

Er... that's not even why I brought it up. XD

I would buy Beyond, even if I had the option to buy both, I would only buy Beyond as ND has been disappointing to me this generation. Uncharted has not appealed to my att all, aswell has no characters in the franchise, while Heavy Rain has appealed me and think that it is a fantastic game, from what I have played on a PS3 in the appartment of my friend.
