I haven't found the time to play over 90% of my Wii games, so due to the fact that they're shutting down the Wi-Fi connection soon - I never will get to play them online... Like it says in the title of the topic, I want to at least try to get any items, unlockables, or achievements that can only be obtained while using Wi-Fi. If you can list any that you know of, it'd be much appreciated.
Also, are there any online co-op games that do NOT allow local co-op with a significantly different storyline or ending (or different cutscenes that can be viewed afterward in a gallery) than what you can get with single-player?
In case you also own a DS, I posted a thread there as well... http://www.gamefaqs.com/boards/925329-nintendo-ds/68936455
There's a fair few Wii games listed there. Off the top of my head Animal Crossing and Excitebike are among the most affected, but we never got an answer as to whether weapons unlocked in The Last Story's online mode can be used in single player.
Call of Duty games - online unlockables (weapons, perks/gadgets, attachments, emblems, titles, . . . . . . . . . . . . . challenges) BUT once the WI-FI is down, they won't even be able to be accessed . . . . - Combat Training (Black Ops) and Special Ops (MW3) will be unavailable even for solo play
Conduit 2 - achievements only obtainable online, and they can be seen from the main screen
GoldenEye - same as the Call of Duty games
The Last Story - unlockable content including weapons, which can then be used in single-player
If you know of any other games or WiiWare with free DLC, please post them! (And please specify if it's all user created and/or if there's official content available from the developer.) Unlike Pay & Play content, any extra DLC that's free now - will NOT be available afterward. - --
