So I spent some time parsing thru Pigsy's homebrew video, and spotted a few new projects:
https://www.youtube.com/watch?v=_lyq6yXhSlU
Castlevania: Rondo of Blood by werton playskin - Pretty sure this is different from the other Castlevania projects listed
Circle of the Moon by Andor
Stinkhead And The Seven Deadly Sins by fifth column [systems]
Street Fighter 3 by RheoGamer - I think this is different from the other Street Fighter projects listed?
These are more tech demo than "announced upcoming games", so take these as you will
Gen Prototype by genprototype
An untitled flying game by Anaël seghezzi
An untitled platformer game by Space Bruce
An untitled shmup game by TheNomCognom
Tempest by SpacePantsGames
Wow, so many new ones, I'll add them all.
Except Gen Prototype and ... Street Fighter III (?),
May be Pigsy got the title wrong since the video's shown is Ryu and a stage from
Street Fighter Alpha (already in the list).
not from Street Fighter III
Ryu (younger than SF2 Ryu) from
Street Fighter Alpha looks like this ...

while
Ryu (older than SF2 Ryu) from
Street Fighter III looks like this ...

Or may be it's still being worked on and there's no video yet?
But why would Rheo Gamer start a new project from the same franchise while the current one hasn't been finished?
Anyway, thanks for your hard work, billybob.
