Well honestly, i just play this game in 2021 and i bought it while on steam sale. At first my impression to this game would be like, hmm maybe this is a civ game with a space theme which im not fond of when they released the space theme for the civ's series.
But at the first time i play in ironman mode, and no turns at all so all moves in real time i was like wait a minute...
And after hours passed my mind blown away by the richness of flavours they offer. You can custom your owns species, ships, and you can be a peaceful species or a conqueror. Etc etc etc
This game is worth to play and Paradox still updates this game, and i found out their dlc's are interesting to check out too because it enhances how you play the game.
But my advice is : Get the game first, see if you enjoy it hours by hours passed. If yes then get the dlc's
