Are you allowed to play using only the first three books, and if so, what is the term for this type of game? If not, why not?
Yes, you can play with any reasonable combination of books you want. The PHB I contains everything a player needs to make a character and rules for pretty much any situation. The player's don't really need either the DMG or the MM, but the DM can limit himself to those sources and not really have an issue. Since the DMG has rules for monster creation, including it gives the ability to add in new monsters.
As for a term for this game, why does that need a term? Should there be a term for a game that has the PHB I, DMG I, MM I and the AV I? Does each permutation of the combinations of books get its own word? Why not just say that for this game, we are only using the PHB I for characters?
