I have to disagree here, plenty of good Wiiware games you can't get anywhere else. My Life As a King is excellent. Also, the Wii doesn't have a hard drive. :P
I'm not sure if you're kidding or not, but for the OP's clarification, the Wii does have a HD, it just wouldn't even impress the 90's. To save more than a few 8 and 16 bit games to the console, not to forget your save games, you pretty much need an SD card, so while you're considering games, don't forget the price of one of those little things in the long term.
Personally, I haven't played My Life as a King, but I probably should. Thanks for the reminder!
I think the poor quality of TellTale's ports can be first blamed on the lack of hard drive space, and then on the fact that the dev team didn't so much as lift a finger to improve it for disc version. By which I guess I mean I agree with you wholeheartedly.
Seconding the vote for Another Code, if only as a Trace Memory fan who hasn't been able to import. :(
No, it really doesn't have a hard drive. It has 512MB of internal flash memory but it definitely doesn't have a hard drive. I guess Nintendo just weren't expecting downloads to take off (my guess is that they thought they'd only be selling virtual console games and Wiiware that that was 'retro' styled, i.e. nothing approaching a disc game). Pretty short sighted of them, I hope the Wii U has a hard drive.
Oh yes, and Sam & Max Seasons 1 and 2 were only ever released as disc games on the Wii, so you can't blame that on limited space. I'm sure ToMI's port would have been a bit less rubbish if they'd had more space though.
One I haven't seen on here yet is Super Paper Mario. An excellent addition to the Mario Franchise! :)
A rubbish addition to the Paper Mario series though. They stripped out all the RPGness!
