The hope is there for value adding options and a skew towards some of the lesser free to play games might help. Equally I will look to stuff like the animal crossing nes games back on the gamecube, some of the ninja gaiden classic modes and indeed the game and watch stuff in some of the DS games. As it would probably happen to the exclusion of those I will probably still call nonsense and have something similar to my last sentence reworded be the reasoning but it would not be quite as sound as it could be.
As for modding if only there was a way of having player data stored on the side of a server..... Granted it might take some thought to do properly with my immediate thoughts being something resembling the PSN rental library approach, some honour type systems (being banned from xbox live is apparently a bad thing according to some) and maybe a direct connection or unique rekeying (profile modding is sub script kiddie level but modding unique content or something with an access token takes actual effort). My only real concern with that is it might make some hacking pursuits able to be targeted with some semblance of legitimacy but that is not a reason as far as most companies are concerned to go down this path. Of course the really good model will repurpose a choice phrase I see floating around (hackers gonna hack) and indeed consider that it would have been given away for free anyway (effort making for a better result even if it just in your head and that we have achievements in the first place and some of the justifications/defences seen for them in this thread alone would seem to indicate just in your head is quite fine to target).
Re the discussion on Kid Icarus two things the first of which is if you can not make a game on the system setup in the style you want then change it (although how one fails to make a version of space harrier I am not sure) I forgot to go there first time but can I reframe the discussion as instead say games that spend resources to do token multiplayer and as much as it pains me to say token co-op. Granted such things might take actual effort which is probably not on a par with some token achievements although modern engines and the end result of some........
