This game is mid on the actual building vehicles part. They are constantly are adding updates that strip away creativity, for example: Pre - Dogfighting era had people building clever contraptions to get their guns to home in on the other player's plane, but now with one update they made all of that obsolete because the guns do that by default now. Another example: Pre - Space update era: People had to find clever ways to balance thier helicopters and motorcycles, but now they added a block that just locks your rotaton on a certain axis.

This Game also constantly shoves DLC into your face. Load up the game, "DLC! GO BUY IT!" Pop up,
go to the menu to select a gamemode, "DLC GAMEMODES! GO BUY THEM!", Start building something, look through your blocks and "DLC BLOCK(S)! GO BUY THEM! And the worst part is that all these DLC's ARE ALL OVERPRICED AND Almost of them have MIXED REVIEWS.

To recap, Building is kind of bad , the devs are activley hindering creativity and are also making overpriced DLC. So after all that do you still want to buy this? If not i reccomend a different game with better building named Scrap Mechanic (NOTE: Its not just about vehicles)

The game itself if fun, however don't expect much new content. while the game has updates every few months, they almost always add 2-5 new blocks, instead if you want to get new content you need to drop tons of money on one of the 10 dlcs.

It is laggy on lower end devices ofc but it is still fun. hard to build good things. i would not say to get it if you have a low end device
