I'm trying to uncover old PC games I used to play as a kid (so they're from the 90s). Ideally I'd like to buy them on Ebay and see if they work on my current PC or, more likely, the older computer I have downstairs. One was Marathon, a first-person shooter game where you fought aliens on their planet. The other was a game where you picked a type of fish and went swimming around, looking for the food you could eat (depending on your type) and watching out for the predators you couldn't eat. Problem is, I can't remember the name of the fish game. Does anyone remember or know if they games would work for me at all?
