I couldn't finish XIII. I got to Gran Pulse, and found there were 60 'hunt the thing' missions and honestly couldn't be bothered. I actually got through most of the railroad-y bits with no problems the second time round (the first time, I put it down after killing Barthandelus the first time and got no further), but when it got to Pulse, I just couldn't do it anymore. I tried desperately to finish it, and put off playing XIII-2, which I had a lot more interest in, so I could try to finish it first. However, a couple of days ago, I picked up XIII-2 and have absolutely LOVED it. Every issue I had with XIII is gone, and I've enjoyed the setting, the plot, the characters, the non-linearity of it all, and hell, even the missions, and they're not all 'go here, hit that until it dies'. So yeah, if they continue it with a sequel, I'll probably get it. But VERSUS XIII, that is a game I NEED to see.
