The whole "PlayStation exclusive" thing probably limits the appeal here. Isn't this primarily a PC forum?
TLOU is hands down my game of the last generation (for the All-Time title, it'd have to contend with RE2 and Silent Hill 2...but it's dang close). Played it through a handful of times. Honestly, the ending seemed a perfect climax to the story, cementing the growing father-daughter bond between the pair, and appropriate - or at least understandable - given Joel's tragic past. As for...
...the rest of humanity, well, let 'em burn.
On a slightly lighter note (though not really!), if you haven't tried the Left Behind DLC, I highly recommend it.
