XIII might be a good game one day, but it’s infinitely more likely that it will simply be a mediocre one. Right now, it’s outright bad. If you want to play XIII, I suggest that you go buy the original release.
It’s flawed, but unlike the remake, it’s a finished product, it looks better, and it’s a heck of a lot cheaper. PlayMagic and Microids can promise all the fixes they want, but until they actually deliver, we’re left with a bad game that they chose to release anyway, and absolutely no reason to take them at their word.
