This brought back a flood of wonderful memories. Tying up my parents phone line with the Dreamcast's 56k modem was a formative experience for me as a nerdy middle-schooler.

- The Dreamcast keyboard made communication so much better - I was studying French, and joined European servers sometimes for the thrill of using the language with real Francophones (VERY rudimentarily)

- I once met someone whose job was composing jingles and writing slogans for a greeting card company, which I found really fascinating for some reason, and I spent an hour peppering them with questions about it

- The lore of the "gladius spike", a supposedly really rare dual-saber weapon that never actually existed

- Being given a treasure trove of the rarest items in the game by a duper named "Cap'n PooBeard"; the drop rates were so ludicrously, absurdly low that I would never have seen some of this stuff otherwise (Chain Sawd, Spread Needle...)

- The fear and thrill of playing with strangers, due to the mechanic that you drop your weapon when you die, allowing others to steal it

- The vibey, synth-heavy soundtrack and diverse biomes

I haven't played it in decades, but I bet that it still holds up. :)
