Wild Arms 2 was my first game of the series. It's still one of the most enjoyable games of the series I played. Everything about the game was done right, except that final boss. Vinsfeld was one of the best villian I ever encounter in a video game. Too bad he wasn't the main villian.

Wild Arms Alter Code: F was fun and vastly enjoyable. I played the original, but never could get into due to the chibi design to the characters in the original. Only problem I had with Alter Code: F was it seem much easier than the original. Also, they gave you new optional characters, but meh, they were extra characters that weren't include in the story any longer once you obtain them.
Wild Arms 3 was also very enjoyable. Clive and Jet totally ruled. While I was wondering why Gallows looked so stupid and had a shotgun that missed the majority of the time and he sucked all around. Villians in this game don't match up to the previous villians of the previous games, but it was still enjoyable.
Wild Arms 1 don't dislike it. I just never was a fan of the chibi designed used in the game. Storyline still my second favorite of the series along with the characters. I also dislike the fact the game froze on me. It's only fourth, because of Alter Code: F. Overall, this game was better than 3 for me.
