Seaman is a wonderfully curious game released for the Sega Dreamcast in 1999.

I love how interactive it is, with Seaman having dozens upon dozens of lines of dialogue that are used to have conversations with him. You get to feed him and adjust the tank temperature too, depending on how hungry or how hot/cold he is. I don't own a copy of the game itself, as I fear failing to take care of Seaman would stress me out too much, but I absolutely love the atmosphere it creates and I love how unique of a creature Seaman is. The player raises him from an egg all the way to an evolved land creature. I myself am still exploring this game, not yet knowing the ending of it, but I am very excited to see Seaman's growth. Seaman himself is a really comforting character to me, which is probably why I'm so drawn to this game.
