The X series has a storied history of being the top in the space trading and combat simulation genre. It has also been one of the harder series to get into with previous iterations offering little to no introduction. With X4: Foundations, it’s very obvious that Egosoft has tried to alleviate some of its past mistakes of being too cumbersome for newcomers, as well as implementing newer features that other space hauling series have introduced.
On the whole, Foundations succeeds in its attempt to be more accessible, but some of the new elements show that Egosoft might have bitten off more than it could chew.
