Mass Effect

Mass Effect is an incredible game with deep lore in a well-built world that begs to be explored and understood. The characters are rich and interesting on their own merits, but the non-humans in particular carry with them fascinating cultural backstories that feel truly alien and yet wholly believable.

I so loved this universe and these people that I played through the game three times in a row and devoured the tie-in novels.

Shame there were never any sequels.

The best of the best. Only one character may be in this tier for a given work or medium. This character... is Mai Waifu.
