I finally got around to finishing this project, so now it is here : The 3DS Download Play Archive!
A total of 32 games are now listed, with descriptions, screenshots and Download Play-specific information.
New games and games I might have missed will be added as soon as possible. Hopefully there will be even more games on this page soon!
Please tell me if there are any errors, some information should be added or if you simply have any ideas for improvements or additions. I want to page to be as good as it can be!
