loco Gold, land of chaos Gold

Human: the most populous race in the Gurhal System and the original race from which the others were derived. Humans tend to be all-purpose, with a good balance in abilities. They are not especially poor at anything land of chaos Gold, and can manage any kind of occupation.

On the other hand, they don't excel in any one area. They primarily live on Parum. Well balanced Skills. 

Newman: Newmans were born of humans as the result of an attempt to create a superior species. Although their physical abilities fall short, their magic and spiritual abilities excel and they are masters of TECHNICs.

If you get bored, System Defense and Valley of Carnage missions on Moatoob are interesting, but not necessarily as balanced for items and gaining levels.

Most Synthesis items sell very well to other players, especially photons. Photons not sold by NPC shops (ie: Ban-photon and Ray-photon) can sell for hundreds, if not thousands of meseta to other players.

As you earn more meseta, you will want to feed your PM more expensive items. This is especially helpful if you're in a rush to get a full-evolved PM, with plenty of time to play PSU.
