I think the big publishers correctly realize that they need to make games look attractive at a glance - the problem, IMO, with this game (in TFA), is that it's just not something that grabs you immediately. And even if Madden N+1 is not 10-100x better as a game, it
has ultimately brought more pleasure (==> utility or wealth) to the world because it properly marketed itself and looked good enough to get anyone that might enjoy it to buy it. I don't think the game in the article has maximized its own potential, and that's a problem...
I'd personally rather see figures for indie games more along the lines of
Droid Assault or
Robokill (check these out if you haven't - maybe a shameless plug, but I'm not involved with either, just a fan!), both of which have the kind of immediate traction with a player that an RPG with graphics that were getting stale a decade ago just can't pull off.
I'm not saying you can't have quality without graphical flair, but come on - you've got to look like your making an effort if you really want to move product!
