OF the Dark Cloulds, 2 was superior, though quite a few people enjoyed the first as well.

My favorite part of 2 was "Crest, The Great Sage." Amazing story arc that was.

And of Wild Arms, I can't vouch for 1, but the rest are awesome as Bunny said. Especially 2 and 5. 2 has an amazing story and great characters, and while the battle system is fairly classic in style, theres enough quirks in it to make in pretty freakin' awesome.

4 and 5 use a very unique turn based sysem in which you move characers in a Hexegon Grid thingy. I have a hard time explaining it, but its simple, fun, and unique.

The wild arms also use a lot of puzzles to solve in order to advance. You get different tools that do different things on the map screen to solve them with. The only other rpg that did that well I can remember was Lufia 2: Rise of the Sinastrals for the SNES.

And major props for the Persona's.
