A lot of the time I play games through good word of mouth, or perhaps the cult following a game may have. After all just because a game doesn't sell great or get eights, nines or tens doesn't mean it is not worth playing. I honestly wouldn't have picked up some great PS2 games like Shadow of Rome, and the Onimusha games, or some of my favorite games like GodHand and Vanquish if it weren't for good word of mouth from fans of those games.
That is why I want to ask the question: if you could recommend one game to us all, what game would it be? Maybe the game is one of your favorites, maybe it just does something interesting, maybe you think it doesn't gets the recognition it deserves. Hopefully it is something that is easy to get and not something everyone has played. But really it can be whatever you think needs to be played by more people. And if something has been mentioned already say yeah that game plus something else you like. Go Crazy recommend stuff like Barkley Shut Up and Jam: Gaiden or Abobo's Big Adventure or whatever I don't care I just want to hear what's out there.
EDIT: I just want to hear people talk about a variety of games, if you want to talk about more than 1 game or a game that has already been mentioned be my guest.
My recommendation would be the Mother games, they have a cult following but haven't taken the world by storm mainly because Earthbound was the only game released here. But Mother 2 and 3 have such a charm and quirk in the writing, and the characters/ enemy design. The gameplay is fairly simplistic and so are the main characters until 3. The simplicity is probably to its benefit, that way you aren't sitting though long cutscenes or wondering why does that character have so many zippers. But still there is something so strange about the games that I just love. Earthbound probably has the most Beatles references out side of Beatles Rockband, Why? Because Itoi is a big Beatles fan, so big a fan he named the series after a John Lennon song. I think the the whole Japanese America aspect of it is amusing and it is one of the few times that kids are the protagonists of a JRPG and it doesn't seem stupid. Maybe it's because Mother 3 would be a good studio Ghibli movie. The humor I find great It is worth mentioning the music is fantastic, plagiarized, but fantastic. How many games give you bat enemies that have battle themes that sample the 60's Batman theme? Only 1 I can think of.
