rampancy: I see what you're trying to say, and I appreciate that. But the blame for that lies with publishers who set games up to fail, either through pushing unrealistic release schedules (resulting in rushed development, like with KOTOR II), encouraging feature creep, or overhyping a game.
And when modders "fix" said game for them, they get let off the hook for any accountability. It does happen and as long as modders offer free help, it's inevitable to happen, because game makers are in the business of making and selling games to make money.
It's a huge monetary incentive to rush a release, get it out the door, then not worry about fixing all the glitches because whatever they miss, modders will fix for free. No need to pay our in house guys to do what modders will do for free. If there's anyone out there (I'm not saying you're one) that thinks a for profit business won't give in to such incentives at stress times then they're living in a fantasy world. When consumers don't hold sellers accountable (and buying crappy products and fixing them yourself is most definitely not holding sellers accountable) then it will always be the case that the quality will drop.
It was the same thing years ago when the internet first started getting popular. Believe it or not, you used to be able to walk in a store and buy a game that worked right, out of the box. But as soon as the internet made providing patches easy the incentive to release unfinished products went up, and then as soon as consumers shrugged and went along with it by purchasing the games anyway, boom, no more incentive to get a game right for release. I'd bet you can't name one game that hasn't been patched in the last 10 years.
And this same incentive will and does work regarding modders. All you have to do is put yourself in their situation. You make a product and sell a product. Then, you begin to lower your standards in making said product to save a few bucks because you know you can fix it later, after your customers have shelled out their cash. If your customers continue to buy anyway, why stop? Then when you discover your customers are not only continuing to purchase your product, but are now taking it upon themselves to fixing it up because of the lower quality, why on earth would you, or anyone else for that matter, not take advantage of that?
