it's a great game so far.
Glad you like it. When you beat it, you can do a New Game Plus, which lets you re-beat the game, but you keep any and all upgrades from your previous playthrough. Be sure to save this NG+ on a separate Save File though, do NOT save it over your original playthrough.
It took me about 12 hours, maybe. I didn't search for Collectibles, but I did look for supplies a lot. 12h is about average time for me I guess, but I like to listen to all the dialogue and Ellie's Jokes, so, yeah.
Do us a favor though, when you beat the game if you feel like expressing your love and thanks for it, there are several threads already up about that.
1. The Last of Us
2. Red Dead Redemption
3. Assassin's Creed II
4. Mass Effect 2
11 hours, but I missed a ton of collectibles my first run through. I spent much of the game trying to be as stealthy as possible because I never knew when I might need those extra bullets/weapons later in the game. When it ended, I just about had max of everything because I was hording so much.
Be sure to save this NG+ on a separate Save File though, do NOT save it over your original playthrough.
Is there a reason for this? I must have missed something here.
