I am so far liking every character in the game, they all have their own personality. Although Nash can be a little arrogant, his magic help can be needed for defeating monsters.
I am guessing I am at more than 50% of the game completion. Here in this gameplay I am about to get Kyle (Jessica's boyfriend) to join in. Once he is in the group, you have a maximun party character count. I like Kyle because he is strong with the sword as good as the main character Alex.
Overall this game is excellent for RPG gamers, I highly recommend it.
