Been fiddling with DLC since it was called expansion packs. As with others there are good ways to set about it and bad ways. I have no problem with on disc DLC -- my windows disc includes the ultimate version of that range but if I buy poor man home edition then I don't automatically get big boy just shy of server/workstation edition.
Extra characters/items/weapons... I will not necessarily praise it but as long as things fall in or behind (though why any sane designer would go behind I do not know) the pareto frontier then I do not mind. If DLC peeps have an advantage other than they have more selection which I have to account for then I have no problems. If DLC peeps can have higher levels than me then as long as they are scaled back to my pleb level (or max level as the case may be) then I do not mind, if DLC peeps are going to have a 10 level bonus over me then second word is off.
Extra maps... hardly ideal but I can live with it. I am not one for online multiplayer though.
On the flip side the free to play model where you can pay to be your chosen character I have no problem with.
Finishing a story. Truly lazy design in most cases and far from ideal but not as distasteful as pay to win DLC for me.
Side story, while you were doing this, post game extra mission, what if everything was slightly different. Always up for that. Cut content/early beta polished a bit and packaged up. Yeah OK.
Stuff like seen in
I would prefer it for free but I will take what I can get there. If it was deliberately cut content for the sake of being DLC then you are invited to park it on this mid digit and swivel if done by someone channelling the inner money grubbing bastard, I am not necessarily opposed to full release and then DLC as a plan from the start but it would be hard to pull off well. If it was "we made the game and then we spent some time after, or the massive beta test that is 3 million players playing for 30 hours a piece giving us good info, and got really good as a consequence, here are the results" then I shall decry the nature of game project scheduling but I will be curious to see what goes.
Because IP lawyers exist DLC. Most would think things like music game tracks which could total hundreds and more, however if you want crazy then look at
train games and what some charge there, let alone just trying to get all the trains -- car games are more popular and provide a similar example but some of the train stuff is bordering on obscene. I still have bad memories of the music DLC cluttering up my releases of the day/week/general release posts, at least before I stuffed it in the music game DLC ghetto (simple pre listings in a spoiler). On the other hand I know IP lawyers exist and the frameworks for it exist so call it resigned acceptance.
Pay to win games. I value them as an idiot detector, not much more. Pay to win but possible to play and compete happily if you instead log in every day and do things, so technically not pay to win any more, I am OK with. Pay for cosmetic, and the previously mentioned pay of character selection or some bonuses that do not provide an advantage as much as another way to play, I am fine with.
It is now the modern world and where my save files take up a level of space equal to an entire ROM I accept there are going to be bugs, patches required and more. This is not an excuse of laziness but it is a reason to see some leeway given. What goes here as far as DLC I do not know. I see several cheap to buy and updated forever mobile games do things that some might call DLC and I am delighted to see rolling release happen as a model for games.
I do wonder what the advent of modern DLC has done as a negative for games. I would say pay to win but I remember arcades/coinops. Trophments have been widely held to bother in game
cheats and things like the skate 2 and skate 3 paid unlock DLC leave a horrible taste in my mouth. With things like heroes of might and magic and doom and quake and counterstirke and unreal tournament (and this list could go on for a little while) we saw some amazing user made content arise. DLC has possibly stifled that a bit, though at the same time the locked down nature of consoles has not helped. I would note that a lot of time extra costumes were once default in games, at the same time I do not care for such things.
