"You know what game had lackluster graphics??? ... Lemmings."
It did? I never thought so.
"Also, Bonk on the VC has horrid graphics."
Back when it came out I remember seeing commercials for it and I thought it looked utterly amazing.
Anyway I'm just making a generalization. Often when a games look like ass, and that doesn't just mean weak graphics from a technicaly perspective but an artistic one as well, you can assume it's not a well made product and thus not a very good game. You should always be open-minded and be willing to try and ugly game if it gets good reviews and such. But here is a game with unimpressive screenshots released by Sega, who I no longer trust to make decent games. It's also a 3D update of a 2D game. Being cynical about it is somewhat expected. If Nintendo showed the same game then I don't think the graphics would matter as much to me. They have a more consistent recent track record and have a history of doing a really good job of updating 2D games to 3D.
