I wonder what approach the companies will take for their next generation.
PS3 added HD graphics, online play, media centre solutions, digital games and movies, DLC, wireless comtrollers and so forth over the PS2
Xbox 360 added Hd graphics improved online play, digital games and movies, DLC, wireless controllers, avatars and so forth over Xbox
It seems likely the next generation will add...
3D, standard
More emphasis on motion control
DRM (which i hate)
Perhaps a focus only discless gaming
Larger community-based online integration into every game
Trophy/achievment expansion into gampelay rewards/content
and if some get their way; buying chunks of games instead of complete games
One approach i would like to increase the longevity of a game is simlar to the VIP packs offered by DICE and EA in Bad company 2, these added new maps free over the course of the year, these didn't feel as if they were taken out of the final game and reserved for us too pay to unlock later, they felt that they increased the 'new feeling' months after you bought the game, this tactic if publicized by the dev and publishers would keep the buyers of the games happy as well a reason to keep the game and a reason to keep coming back for a new replayability.
Unfortunatley this seems like DLC that isnt paid, for which it is, and thusly companies wont want to lose money they could take from the consumer.
The EA/DICE way seemed more friendly to the consumer like you were being rewarded rather than fleeced.
Perhaps when you buy the game you could pay £10 and over the course of the year new content is released and downloaded automatically. Like a one-off subscription with the guarantee of future decent content, rather than solo DLC released for increasing cost each time.
Or perhaps an easier way is to include trophy/achievements unlock rewards, so lets say you unlock a bit of content after doing a certain amount of trophies/achievements, this would be a great idea i think, it implements trophy/avhievements into the gameplay itself, especially since going after trophies/acheivements is quite popular now.
