Turtle and Lordnine, it doesn't look like they're going to have any problems hitting the Co-Op Stretch goal. In fact, I won't be surprised if they break $1 million. Kicktraq currently says $750,000.
They don't really have much in the way of swag, which may be both good for them financially (apparently that's a big drain on Kickstarters) but will keep their numbers down. But I still think they'll get some good bounce at the end of the project.
New Stretch Goals for $320,000 up to $380,000. $400,000 is still Co-op Multiplayer
New Class - Geomancer: Manipulate rock and stone to bolster your city's builders, flattening or raising earth as the cause demands. Craft tireless golem workers so everyone else can take a much needed break.
She put green lights in their empty eyesockets--a fanciful touch, but she felt it gave them character. Now, she checked each rune for dust, noted every crack for the touchups she'd handle tomorrow. Powered them off, one by one. Slowly, green lights dimmed to black. "Good job, guys! Finished the whole square in just two days!" She dusted her hands, patted each fondly on the head, and shut the warehouse door.
In the dark, one pair of lights swirled back to life.
Enemy Faction - Elementals: When conditions are just right, unstoppable giants of fire, rock, ice, and air rampage across the land, destroying everything in their path. Appease them or prepare your defenses...
Verne Earthwalk fought to control his voice. "My Lords," he managed, "when I said that your incessant digging made the earth angry, I meant it. Literally."
New Class - Engineer: Fiendishly complex traps. Steam pumps. Black powder. In his moments of genius, this Master Craftsman boosts your town's productivity with miraculously advanced tools and weaponry. In his other moments....
"With steam, human ingenuity, and enough pipes, anything is possible!"[/i]
Seasons!: Horde food for the winter and farm up a storm in the summer as the four seasons cycle over your town. Building, farming and fighting all gain new depth as rising temperatures parch the land and falling snows drive your settlers indoors.
"SNOW DAY!!!!"
Then out at $500,000:
Alternate Planes: Many dimensions lurk beneath the fabric of reality. Lured by the promise of untold riches and arcane secrets, your bravest townsfolk open portals to previously unknown realms. What could possibly go wrong?
Through the door I saw... the sky. The sky at night, when the stars fill one end of the horizon to the other. Except... the stars were ordered in perfect rows, like corn in the field. And little round plates studded with rubies dashed around between them, jabbing lances of light at each other. One of the plates... flew apart as I watched. In a ball of fire!
...No more mushrooms for me.
