Warp drive machine. You get a tiny space to build on and every so many minutes you get teleported to a random new planet. Everything outside your space is left behind. Research and crafting efficiency is balanced around this.

Seablock. You refine just about everything from mud you suck up from water requiring you to build huge mud processing factories to get a trickle of metals and other stuff.

Ultra cube. Every recepie requires an ultra cube and you only have one. It does not get consumed, the crafting speed is ludicrously high, but you'll need to juggle the cube around in your factory.

Finally you Can just add a bunch of extra planets to the original space age.
