No problem. Similar line of thought? Yes. But not really comparable, especially as the car one could result in people being killed.
I'm not saying that devs want to release games like that, but it is possible. It isn't very good practice of course, but it does happen, such is the pressure of the heads to meet the deadlines.
I just wish the gaming industry as whole would pay more attention to product as opposed to profit. In a nice ideal world, having a great product would lead to profit. But it seems most companies just can't afford to wait that long anymore.
Don't get fooled in to the assumption that games make big profits. Some do, but I've known of big titles that haven't generated any profits. Heck, EA have announced losses in the pass of about a billion. Look at the recent closure of Transmission Games, biggest and longest running dev in Australia. It's a tough industry, it really isn't that glamorous. We do it because we love it.
I hope i've not given you the impression that all devs work in that manner, but I know of some that do, because it really is easier to do that than delay the release by 2 months and miss a lot of sales and potential targeted release dates (ie, Christmas, a particular event that the game might be based on, etc). I personally don't mind playing a game for a couple of months, knowing that it will be improved in a couple of months. It's risky and not something any body wants to do, but sometimes that's the hand you are dealt. In a business that already struggles with piracy and the pre-owned games markets, taking abit of damage limitation is necessary.
Imagine where GT's status would be, if GT1 or GT2 had been as buggy as Shift. I'm willing to bet, there wouldn't have been many more sequels.
P.D. does it right. Release dates be damned. If it isn't up to par, they don't let it out to the public.
But can you seem the damage that is being done by their "delay". I think most expected GT5 to release at some point in 2009, back in 2005/6. They've never officially announced a date, and with very good reason. Could you imagine having to tell millions of customers you aren't going to release within 6-12 months of the official release date? Particularly on huge projects like GT5, when you could spend so much time tweaking the game. This is why Kaz has been saying, "we can release any time we want to" for what feels like a couple of years. Many parts will be being tweaked, then asked "is it doing what we want it to?". Reviewing and analysing data and comparing it to your set objectives is an important part of QA. You can tweak for ever, setting values just right, finding the right combination's.
