Hmmm, well digital downloads don't impress me. My thoughts on DSIware are similar to the PSPgo: I don't like it, I'm not supporting it.
Simply put I will continue to buy games that come on chips/carts, and if they stop producing them I'll go back to carrying paperbacks with me for entertainment on the go.
The only way I might fully support 100% digitally obtained gaming is if every single platform went that way, giving me no choice... and even then I might very well wind up quitting.
To put things into perspective, I probably spend a couple thousand dollars each year on gaming. I'm disabled on social security and only get away with this because I live at home currently, I doubt it will be something I can do indefinatly. It's how I pass the time.
Let's say for example that things continue this way though, I spend a substantial amount of money, but the gaming industry wants to give me increasingly diminishing returns. Both in terms of less control over my own property, but trying to get me to pay subscription fees, and register for more and more services, with greater dependance on needing to spend money in online stores to get all the content.
The thing is that not only do I not own any physical media with things like DSIware, but I also feel that when things like this are succeeding it prompts the companies, even the "good" ones to to get progressively greedier. I'm waiting for Nintendo to advertise that they want people to pay for a premium service for the right to buy things from them. I mean heck, we've already got Bobby Kotick (in an article just put up here) looking for ways to attach subscriptions to "Call Of Duty".
I mean, as "cool" as these bite sized games are, I can't call them a "best kept secret" or anything of the sort, since really I think they are a degenerative interest. Heck, at the very best your going to see price creeps like you did with X-Box live with people demanding more and more money for less and less. I remember back when "Braid" came out and it was selling for $15 instead of $10, but it was declared a "rare exception".. well guess what, getting away with that means that pretty much all the games are going for $15 or even $20.
Well, enough rambling. I guess my overall point is that I don't think that any kind of downloadable or digitally obtainable game should be being lionized by anyone.
