Shopping on D&D Classics today I noticed that the Player's Handbook, the Dungeon Master's Guide, Monster Manual 1 and 2 are all missing from the catalog. However, the Rules Compendium is available. The description implies that it includes most of the content from these and other books:
Tired of hauling all of your D&D rules supplements to the gaming table? Having trouble finding the rule you need? This supplement takes all of the roleplaying game's most important rules and presents them in a single comprehensive, easy-to-reference volume for players and Dungeon Masters alike. In addition to presenting the rules of the game, this supplement incorporates official errata as well as behind-the-scenes designer and developer commentary explaining how the rules system has evolved and why certain rules work the way they do.
Right after that it suggests that you still need at least the PHB, DMG and MM however:
For use with these Dungeons & Dragons core books: Player's Handbook, Dungeon Master's Guide, Monster Manual.
The only definite things I can tell that are missing from the RC are "class-specific options and feats." What else is missing? Do I still need the PHP, DMB and MM if I have the RC? And if so what's the point of the RC?
