I guess to name one not mentioned in the OP Konami. Although they've been letting their franchises languish in the recent years theres so much in their back catalogue that despite having a few collections out already theres so much more. Maybe a best of 16bit arcade collection or the beatmania arcade series.

Old games best games. DOOM2 The Legend of Zelda: A Link to the Past Diablo II: Lord of Destruction DR. Mario Legend of Dragoon

Megaman Legends really needs a remaster/rerelease its been too long capcom. Also getmeoffthemoon!
