Man, Star Control 2 was my favorite game to introduce friends to during the BBS days. Two player melee over a shared keyboard! The music in SC2 was top notch MOD/XM music back when trackers were starting to form a genre. Beeps on computers were the norm but you could hear a drum track over the internal PC speaker in this game. IMHO Tunic is the only game that came close to the wonder and awe of exploration and discovery. Absolutely a masterpiece.
Babu's game room has my favorite YouTube review. I'll let the bot pipe the link
