no, you just need youtube for that.
That's the best thing ever for games that have bullshit multiple endings. Back in my day, you just read about endings online on someone's angelfire website or in the primitive version of Gamefaqs. you know, the one that had the graph paper background?
So you either had to absolutely love a game and have infinite free time (like a teenager for example) or you just had to look it out and hope there were screenshots or a detailed explanation of what happened.
So thank goodness for youtube. I can be a crappy gamer who just mainlines a campaign and then load up youtube to see what endings I missed, like i did with gat out of hell and New N Tasty. Because I aint got time for that.
