I'm pretty much in agreement that they should just be part of the regular DS list, since they still work in a regular DS. But at the same time, maintaining a DSi listing for DS games that have special enhancements for the DSi, but still work in a regular DS is also kind of important just for clarity. Then, only create an actual DSi listing for games that won't work on a regular DS at all.
I was thinking DSi enhanced games should be labeled DS+i as opposed to just DSi so as to designate it as a game that works in a regular DS, but is enhanced for DSi. So in total, there would effectively be 3 categories of DS games; DS, DS+i, and the eventual DSi category for games that would NOT run in a regular DS, but DS and DS+i are in a combined list.
So, with that said, put the DSi-enhanced games in the DS listings, but have it where it is easily selectable somehow via "Releases" for peeps who want to quickly determine which games are DSi-enhanced. It would mean that there will have to be some renumbering going on and some finagling in the forum to set it all up for doing releases and stuff, but the sooner we get the structuring in place, the easier it will be to do the renumbering. This way, there won't have to be a new category created until true DSi-only games start to appear. The current category could just have a switch to sort for, DS, DS+i and Both. Worry about an actual DSi listing when DSi-only games appear.
I don't know, makes sense to me, though I have no clue how to implement such a thing.
Leave it to Nintendo to throw a monkey-wrench into the works.
