Okay, maybe it's indeed better to name a couple for some more guessing time per game. I'll do five, and swap in new ones when one's guessed or has to be revealed. So here's five games;
#50: This game as rushed to release, which sadly caused much planned content to be cut or left unfinished, especially near the end-game. Fans however, made many mods, which restored much of this content.
#49: A black-box game of a sport that has the wrong name in Europe.
#48: You actually want to shoot the character you can't shoot.
#47: It looks like you stranded on a lovely island, if it weren't for that bird.
#46: After you seemingly died in your sleep, you find that you can return to your own world through a mirror after first finding the sun, moon and the stars.
#49 Soccer on NES is the only one that comes to mind
