I'm personally finding the game easier then the rest by far so far. Money hasn't been an issue as of yet. I'm still sitting on over 7000 with pretty much everything I need already bought.
Just a tip for the side line characters if you want to level them up and not use them. More then likely you will need one at some point and you might have to grind for levels. The tip is before you turn in your missions change your party to just those party members. All that experience goes right to them and don't be surprised if they go up a level or two depending on how much experience you get. I've been doing that and they level up pretty quick!
