I hate to say it, but I have to agree with you on the point that graphics matter. I try to maintain that I believe quality of graphics has nothing to do with the quality of a game, yet I find myself instinctually glossing over games that don't have eye-catching graphics, and stopping only on the ones that are fun to look at. There's no getting around it, your would-be players will skip past your product if it doesn't look the way they need to to.
