abandoned by developer with absolutely zero progress in more then a year. shame.

update the damn game, its been 3 years

The best game for creative stuff, not best for mechanical tho.

Immortant stuff that i found frustrating.

Glitch weilding is most of the time neccesery. But, i dont really have a problem with that, it even gives more creativity in some cases.

At high speeds colision doesnt exist, objects literally past through each other at high speeds.

At high torque, something that hole purpose is to held stuff together with some properties, starts breaking, for example bearings, at high torque center of object can shift away from center of the bearing it is connected to.

"Suspension glitch", if you apply some power to the "wrong" side(for example try to stretch it, or apply pressure diagonally) of the spring it would straigh up do something unimaganable. But sure, some people use it to balance or even make the whole creation roll, pitch and yaw. But for example in a "double arm suspension" for vehicles, you need to look the internet to find the variation exactly for this game, Scrap Mechanic, that would do some woodo magic and remove the "suspension glitch". Without it your vehicle "will fall slowly", this behaviour is not about changing gravitational forces, but rather is giving an asymmetrical force to the direction that is close to be exactly upwards, but never exactly upwards.

Because of the stuff above making "mechanical" stuff, like gearboxes or even differential cant be done for a real practical use. And for now, the only way to get some way to feel like you have a differential is to use a gas engine, its fine, but every other type, like electric engine, or even "the best modded engine, smart engine" behave without a single Thought of other wheels or horsepower. Its straight up gives torque and speed. The only way it couldve been solved, is by devolopers of the game or modding community, to make either a "differential block" that would have 1 input and 2 outputs that would behave like a differential, or make an system that would split the engines power across of the wheels and trying to give them all same hp, but for example in some scenarious less power+more speed or less speed+more torque for particular pairs of wheels.

In some creations from the workshop chaging the angle of steering is locked, i think its completely unnecessary and makes live harder, for example i would download vehicles and try to put on them some other designs of suspentions, that requires me to delete old wheels and bearings with suspension settings, but because of this i need to delete the old drivers seat to and relink everything to it.

Good part:

Theres 3 limits of creativity:
1. Those mechanical limits, i think most of you wouldnt even notice or be frustrated because of that stuff.
2. Your own pc`s specs.
3. Your imagination.
Basicly, if you imagined the creation that wouldnt required those mechanical stuff and is not gonna be extremely funky with freefloating blocks that would result in the friction and collisions, you can make it in this game.

Extremely good modding and builders community, they are insane, some of the builds are completely vanilla, but yet so beautiful (I love that apollo evo with piston engine), just because of the ability to place stuff into each other people create insanely detailed looks and bodyworks for any creations. A lot, i mean a lot of quality of life mods and other mods give great details for your creations or can introduce air resistance and be used to make a plane that would actually work on Bernoulli's principl and not just "many thrusters go brrrrrr".
