Pros
Pro Easy to build
Space Engineers makes it easy to build any items or objects making sure any skill level can easily have fun in game. All one needs to do is select what they would like to build from the menu and then choose the parts they would like to add.
Pro Destructible ships
Players are able to smash ships into each other with satisfying destruction physics.
Pro Prefabricated ships available in game that are modifiable
For those that do not want to build a whole ship from scratch there are prefabricated ships available upon start that are also modifiable so users can customize to their liking.
Cons
Con Servers are a "lag hell"
Due to the nature of physics simulation of custom built ships, the game requires top hardware to host the game, still making it a "lag hell" if there are more than 10 players.
Con Still not a whole lot to do
Being an early access game there is still a lot of missing features such as missions, thus leaving no much to do other than the free building mode.
