Play as your favorite-anime-at-some-point-in-your-life-if-you-were-born-in-the-late-80s-to-90s main race, the Saiyans. Live above ground, off the fat of the land, growing armor from the land, importing senzu beans from elves and watching your citizens randomly shoot ki blasts at ravens.
Play as an Adventurer, and discover the secrets of the Super Saiyan. Watch as your best friend dies and learn to be a super saiyan from that! Or maybe just train a bunch against badgers or whatever and learn from that, too!
Defend yourself from the semi-fearsome Planet Trade Organization, headed by the almost-fearsome Frost Demons.
Protect yourself from the actually-fearsome Bionic Androids, and hope not to fight the holy-crap-I'm-dead Majin or the "OH CRAP OH CRAP OH CRAP" Legendary Super Saiyan.
Laugh at the Makyan who wanted to be God of the planet who wished himself to be immortal only to find that immortality isn't fun when everyone is stronger than you anyway.
Watch as all your saiyans turn into giant monkeys every full moon without fail and stop what they're doing, going insane if they're in a mood, giving birth to children that are more powerful than Super Saiyan 3s if they give birth while giant monkeys.
Use DFHack to check the power level of your opponents with the "scouter" script. What does the scouter say about his power level? If you're perfectly average, 4900. If you're a honey badger, 99. You'll have to learn any higher power levels yourself :V
