While i do love base building, there are many ways base building is done in different games, like:
(Descriptions under names, when clicked on.)
Block-based
7 Days To Die has really neat block-based world and base building. With block-based concept, you can make any shape base you like. Also, besides collecting different resources, you need to combine them to make better resources so you can upgrade the block (wood, reinforced wood, cobblestone, concrete, reinforced concrete, metal) to give it more HP. You can also paint each block to suit your needs and there are also predefined models (e.g cupboard, table, couch, bed, TV, faucet, lamp) to complete the interior.
You can either take over existing POI and improve it to make your base (as i did) or let your imagination to flow and build your base from scratch.
Another popular game, that uses block-based system is Minecraft.
Section-based
DayZ has section-based base building with predefined models, e.g door, wall, foundation, tower, weapon rack, storage box etc and besides assembling them from resources, players can only change the placement of them.
Another popular game, that uses section-based system is Rust.
Module-based
Subnautica has module-based base building where you can build your base module by module (aka room by room). E.g add observation dome (module), sonar module, vehicle bay module, section of corridor etc. Most modules can be connected to each other to build one big base.
That method fits very well with Subnautica but doesn’t give that much freedom as block-based method would give. Then again, players don’t have to build their base brick by brick (block-based) or wall by wall (section-based), making it easier to build your base. In Subnautica, there are also predefined models for interior furniture.
Another popular game, that uses module-based system is Astroneer.
Base improvement
Mad Max (another game by Avalanche Studios) has base improvement rather than base building and player has no control over the design or placement. Either build it or not. But to build it, you’ll get mission from NPC and once you complete that mission, NPCs in the base itself, are building that improvement.
For the Mad Max setting, i think it works very well since in there, you’re mainly on the move rather than settling down in one specific area (similar to GZ).
Another game, that uses base improvement system is State of Decay 2. In there, you can also choose the placement of individual rooms. Within your base, there are predefined “slots”, where you can build either “small improvement” or “large improvement”. These also break down to “indoor slot” and “outdoor slot”. But you are free to decide which improvement you want to build to which free slot.
Though, i don’t have a specific preference for base building method. I like each method in one way or another. With base building, it all comes down which system is used and if that system suits the game’s needs (not my needs. I’m flexible on that part).
For GZ, i would prefer the base improvement method since it seems to fit best with GZ. Also, it would give us missions to do, to improve the base along the way. While it actually isn’t base “building”, it also doesn’t require a lot of time on player part to “complete” the base, like the first three methods require.
