It's amazing how that game got both more coherent, but still incredibly convoluted. Still prefer it to 13.
I'll never understand how people found XIII's story incoherent and XIII-2 an improvement in clarity. They may say the word "l'cie" often, but that doesn't add to the confusion past the first couple hours.
There's also that mission 24 which give you BOTH CP and money, which is an interesting alternative.
Also any guide with the ideal weapons for each character? Is time to upgrade some shit.
There are no "best" weapons in XIII. In general, upgrading a weapon will just amplify their base attributes. So a balanced weapon will upgrade to the ultimate balanced weapon, a low-STR-high-MAG weapon will upgrade to the ultimate low-STR-high-MAG weapon, a weapon with low stats but a special ability will upgrade to one with relatively low stats and a stronger version of that ability, etc.
So if you want Fang to be a STR beast, upgrade her highest STR weapon. If you like Lightning's ATB Charge weapon, then upgrade that.
There is a simple weapon upgrade calculator that can help you make the most of your gil/components, though.
Imo you shouldn't bother with that. Seriously. It's a waste of time. Get to the end of ch11, get Death, grind Adamntoises, it's much more productive. I wasted hours on it and I regret it.
Yeah, you can definitely get through Gran Pulse and beyond without any grinding. If you're having trouble though, then feel free (it will also help you get better at the game, which will alleviate the need to grind). The game definitely starts demanding more from you there.
