In video games of this time we have dlc or downloadable content these can range from costumes to characters or even stages, but what is a good idea for how dlcs should be done? This is my answer to that question
first is price, I really don't like paying $5.00 for a costume or costume pack it fells like a waste even if the costume is awesome looking, the way I see it costumes and wallpapers should be free to downloadbecuase they are just for looks they don't enhance the experience any they just make you look cool. If it is a new character or stage price it based on how people react to it for example lets say that capcom tells people they are releasing megaman for ultimate marvel vs capcom 3 and people react with cheers and praise for that one you could charge more but not past $15 same with stages.
second is content, you can't just release a dlc with very little content and expect people will want like it, putting effort into a dlc is imperitive if you want it to succeed take for instance festival of blood and harley quinns revenge those were unbelievably successful why becuase they were well made this can be said for all types of dlcs becuase if a costume is uninteresting nobody will want it.
finally should you release a dlc instead of making a new game, this depends on what you intend to add in the new game if all your gonna do is add 2 new characters and a new stage releasing that as a dlc would the wiser course of action however if you build another game all together and combine it with the first then making a new game will be a great idea, capcom is a company which is notorias for making a new game when they should just make a dlc instead( ultimate mvc and super street fighter4) if you need a good example of what they keep doing watch the angry joe show rant on youtube where he talks about ultimate mvc, a game that I feel has properly done the new game with added content thing is dynasty warriors 7 xtreme legends, with xtreme legends you get 2 new characters, a new mode and, a ton of new maps plus the ability to remix which adds the story mode and conquest mode in dw7.
This is my honest opinion of how dlcs should be done in the future it would be better than charging$5 for a costume pack and would have people buying dlcs more.
