As you should know this game is free to play, but you can buy niodes to get you a leg up on the competition. I write from the point of view of a player who have played for a year+, and bought few niodes.
This game is set in the far future, warfare is rampant, and you are a mercenary piloting a mecha. As you progress and gain experience you can control more mechas and lead your own unit.
I would like to start with a discussion of the resources of the game, some stated and some you maybe didn't think of as resources. The basic resources you need to buy bases, equipment, weapons and mechas are ferrite and bioptics. To get better stuff you need crystals and/or niodes. A lot of things you do earn you xp, in addition there are times when you get niodes, crystals, bioptics and ferrite. There are two more resources you should be aware of; friends and skill points.
FERRITE: you will get a lot of this, used to buy/upgrade things, usually as a filler.
BIOPTICS: a bit harder to get, you might be lacking it at times, used as above.
CRYSTAL: depending on your playstyle, you will get little or very little of this.Used to buy better mechas, equipment and weapons .
NIODES: very hard to get, unless you buy it. Can be used for buying the best weapons/mechas/equipment. Also can be used to give you more fights now, repairing mechs now, or getting your mechs upgraded now.
XP: You will get some almost every time you do something successfully. After gaining a sufficient amount you will go up a lvl, and gain 2 skill points.
SKILLPOINT: used to improve your abilities, piloting heavier mechas, doing more damage with a type of weapons, getting more energy or improving the armor value of your mechas.
FRIENDS: the other people you are friends with on the internet, provided they also play Mecha Galaxy.
