Since it seems some people are discounting certain games from the discussion by whether they were obscure or not, just remember that the topic is asking for games that "were not that popular". That doesn't mean a game HAS to be obscure or rare, just not that popular.

@Tron 2.0: Yeah, Capcom threw alot into making a VJ a success(think I mentioned that). Do you remember when they had a Viewtiful Joe pro wrestler wrestling at some smaller pro wrestling shows in Japan? Pretty unique way to push a game, eh? Talk about thinking outside the box haha.

@Schiggidyd: I mentioned Cubivore and I'm glad I'm not the only one who remembers it. Very fun and about as unique as they come. How many other games have a dedicated "poop" button...

@RCM: Beach Spikers! That was a fun one too. I don't think I got as good a deal as you did though. I think I paid 20 clams for mine and I consider that a very fair price for it.
