The thing you hated about Banjo-Kazooie: Nuts & Bolts, which is actually cool and your opinion is bad
I am not ashamed to admit this: I loved the Gummi Ship in Kingdom Hearts and I loved the vehicle construction in Banjo-Kazooie: Nuts & Bolts. Something about taking big chunks of brightly colored material, putting them together, and then riding in the finished product is really satisfying to me. Maybe it stems from a childhood of playing with LEGO sets.
TerraTech takes that basic idea, but puts players on a procedurally generated alien planet and tasks them with collecting resources, presumably to build more goofy vehicles and tear apart the natural resources of the planet with even greater efficiency. Also, other corporations are out for the same resources, so naturally we will have to blow up their stuff.
The nice thing about this Kickstarter campaign is that TerraTech already exists in playable form, so you can try it before deciding whether to send some money in Payload Studios’ direction. Should the project get funded, money will go toward implementing multiplayer, which is notably absent from the game in its current state.
