Thanks for the list.
Actually some of those have pages already, EG Cavern quest is in compilation 1, others like Audio rally racing, moto championship, Textspaced and Yugio mud are in the pipeline and are going to get entries soon.
Btw, where did you get the idea the yugio mud wouldn't get an entry? I never said it wouldn't, only that hadn't personally got into the game because of lack of documentation and complexity, please don't confuse "games dark plays" and "games that get added to the db" since while those are two related categories, they're definitely not the same thing at all.
Also though remember that "accessible" criteria. Rgouelikes like stone soop won't be getting pages so long as there isn't a way to review the screen, and muds only get pages if there is some degree of screen reader adaptation to the output (since if we added each and every mud people played we'd turn into the mud connector).
Likewise, games need to be somewhat complete, and last I checked I wasn't sure of the status of some like dark defender and 2d platformer.
I will admit android titles are more difficult, because I don't have an android device to test them on.
With titles for the Echo, I am not actually sure, since on the one hand there are games like vortex, six swords and starlanes that definitely need entries, on the other there are a hole bunch of smaller word or trivia games, and what the cut off here is I'm not sure.
As I said, the db will pretty much always be a work in progress and likely there will always be games that need adding to it, but its having the resource there that counts, that and making constant updates, and I freely do admit the last few months I haven't done as much as I should've done.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
