My local EBGames consistently try to rip me off with preorders and trade-ins. Pathetic things like adding $10 on to how much the initial deposit is. I normally wouldn't go there anyway, but because they get their games straight from Australia they can evade Monaco's peircing talons, sneaking reasonable quantities of Good Games past Monaco's disdainful eye. None of the employees know anything about the Cube (small talk: "have you played Metroid Prime? I heard that's good."), or really any other console, and they have a strange, unexplainable inclination towards curt and rude behaviour (one guy kicked out my friend because he kept on asking to buy the Zelda bonuc disc seperately.) I've seen a second hand game selling for more than four times what they payed for it, but they sold Skies of Arcadia (a very rare game indeed here in PAL land) second hand for only $80 (that's 55USD, most new games are 90USD.)
Normally, perhaps, the rise of another compeditor might have some positive effect in promoting competition by threatining to break the existing monopoly, but one must remember that matters are never quite normal when dealing Monaco Corps. You might at first suspect (expect, even) that even the most standard of proceedures might be initiated to combat the competition - marking down old games, introducing player's choice, not selling GBA titles for over twice the US retail price - but nay, Monaco look down upon said tactics as their market shrinks ever more. As they typically only send about half the requested units to retail stores anyway, there'll most likely be a brief period in which the stores that haven't been run out of business by EB will recieve a larger proportion of their requests, but I'm sure Monaco will catch up sooner or later. At best, they'll drop the distribution contract, and no games at all will enter the country for a brief period until Atari picks it up, at worst they'll keep the contract but cull the distribution area to Auckland.
NOTE: I actually don't know how much of this is NAL and how of this is Monaco, but I was suffiently pissed off to to ignore this at the time of writing.
