Played through Wild ARMs 1 and 5. Always wanted to try 2 but haven't gotten to it and couldn't find it when I was younger.
Wild ARMs 1 was great. For whatever reason, a lot of those pre-FF7 era PSX RPG's I just can't get enough of. Vandal Hearts, Suikoden I, Persona I, Wild ARMs 1, even Beyond the Beyond...anyway. Wild ARMs had a great world map, reasonable challenge (some of those Boomerang battles are nasty), great extras at the end of the game. Ragu Ragula in the Abyss was a hell of a challenge.
Not a big fan of 5. Dean kind of reminds me of the Hero from Tierkreis with his cheesy sayings that get old 1 hour into the game. Someone said Carol, I forgot about her because I never used her...wow, she was a terrible character. Saving grace for the game are the cameos (like someone else mentioned) and all the end-game stuff. The four secret dungeons were tough (again the Raguragula battle is a wild ride in this one too).
Kind of like Suikoden, I think they disbanded the WA team? Not sure though. It was a solid series. One of many where I enjoy the earlier games far more than the newer ones (like the Suikoden's, FF's, Dragon Quests, etc).
