Impressive & very polished for an 'Early Access' game. This game does not hold your hand & will frustrate those who lack imagination & dislike puzzle type decisions combined with problem solving elements. It is a pauseable 'rts' while playing against a timer of sorts. Overwhelmingly Positive on Steam for a reason.
Playing this on a win 7 & win 10 gaming laptops, I have not been disappointed. Even have had a few multiplayer games using the GOG version vs a Steam user...with no issues!!! This is an amazing blend of a traditional 4x set in the ancient times, combined with a little Crusader Kings flavor. The game mechanics are so well designed that playing one's turns is a breeze. The plethora of game options to include multiplayer lobby options (it offers hotseat like the old days) solidifies this as a must have for anyone that likes/loves this genre. The 'devs' have seen to it that modding is allowed & that can only mean this game has a bright future in the same way that 4x classics like Civ IV have withstood the test of time. I will end with how impressed I have been with how stable & bug free it is since the release on GOG & Steam. I own the Steam version, as well. Simply put...4x Game of the Year, imho.
No pc game is perfect, however; as 4X Space sims go ISG is as good as it gets. The developers are at the top of the heap per this genre & continue to improve an, already, wonderful & deep 4X experience. Surpasses MOO 2 as the standard to be compared to. imho
I own the Matrix version since day 1 (June 4th, 2020). This is, simply, one of the best 4x pc games on the market. What is even more amazing is how young this gem is & with a great developer...all is well for its' future. Some struggle with the UI (no clue why) & complexities of the logistics. (which are superbly done) As good as this game is 'solo'...it is even more fun in 'multiplayer', either via sending a small file email or playing 'hotseat'. Per 'hotseat', no need to be connected to the internet like some games force you to be.
