True. But delaying a release is a common occurence, and usually well respected. Also - having a team that manages the feature list to ensure that the features that are delivered are done (often at the expense of more superfluous features) is something that happens in every. single. game.
Even games with preorders are sometimes pushed back...that just happened with No Man's Sky.
Although true I would argue that 90s games were buggy pieces of crap for different reasons, typically, then AAA titles of today.
Perhaps, but I wager that almost all of the reasons are exactly the same, the usual reasons why a product turns out poorly (rushed production, inadequate QA, unfocused dev team, heavy-handed publisher interference, etc etc)...none of which have anything remotely related to preordering.
And I respect that there are lots of reasons to preorder. The biggest one being the % discount. I remember being a cash-strapped student that jumped at stuff like that. Hell, I remember being a cash-strapped new-dad that jumped at stuff like that.
And I respect that there are plenty of reasons not to preorder

There are plenty of times I've chosen not to preorder myself for quite a few of those reasons. I just disagree that the particular one we're discussing is a good one for the gaming community as a whole
I don't think that any one person choosing to preorder is actively lowering anything. I think that the pre-order trend overall lowers the quality of finished games. I respect that whether for financial reasons, or time reasons (pre-downloads are awesome) or any number of other reasons preordering may be the right decision for the individual.
I don't want to reinvent the wheel. You can honestly Google it and find articulate people explaining it better than I ever could. Few people claim that Preorders are "good" for us gamers. I haven't seen one, but in a world where people tell me the earth is flat I'm sure they are out there.
That's just the thing...I've had this same discussion with plenty of people over the past few years and I've never seen any compelling, hard
evidence that preordering actually lowers the quality of finished games. I've heard plenty of arguments, plenty of examples of poor-quality games, but none of them - not a single one - could preordering be reasonably claimed to be the reason it turned out poorly. I haven't even seen good evidence that it's been a contributing factor. Any of the factors I listed before arguably were the reason for poor games.
There seems to be a general
feeling among many gamers that preordering is bad for all sorts of theoretical reasons, but there are plenty of theoretical reasons for why preordering could be a good thing too.
The point is it is an old discussion at this point with "proof" a-plenty. Unless you need a scientific article reference for proof... then no... no proof. But again - no one can "prove" the earth isn't flat to some people.
In anycase - I enjoyed your counterpoint.
But there isn't proof OR "proof"

at this point I'll be happy for a single example of a game which was ruined by preordering. No peer-reviewed study needed!
And yes, I am also enjoying our discussion
You're trying to convince us that paying for something that isn't finished with a long history of said product remaining unfinished is somehow having a positive effect on it being finished. However, once the product is out the incentive shifts to DLC and future titles, not fixing the release state of the game past a minimum standard.
Here's an important point - I've never claimed that preordering is
good. I've just disagreed that it's
bad. You still haven't provided any evidence that it is.
I'm of the opinion that it can be good or bad on a purely personal level for a host of different reasons, all of which can be quite valid.
do you think this is comparable though? i think a better analogy for what's being complained about in the gaming industry would be releasing a movie with certain parts of it cut out and replaced with static. an unfinished movie that people pre-ordered tickets for would certainly influence people's decision to pre-order them in the future, and rightly so
I'll grant that there are certainly a few examples of games with content obviously ripped out for DLC, but on the whole it seems that most games aren't developed like that. A lot of DLC...even Day 1 DLC...is developed
after a game goes gold (sent to the manufacturer to print the disks) but before it goes on sale. There's usually a good couple of months during that time when they work on Day 1 patches and other content which can't go into the game because it's already shipped.
So, I find that particular argument unfair to the developer and the publisher because it's based on a generally unrealistic view of game development.
