Star Control 2 is the greatest game in all existence! Yes, it's a bit grindy for today's kids, but so much space to explore, so many wonderful aliens with tons and tons and tons of fun fun fun dialogue, billion things to do and a very fun "spacewar on steroids" combat. The best part? It's open source now, just find yourself "Ur-Quan Masters" and don't forget to download the speech pack. Acting is surprisingly decent for such an old game
