Being a great fan of D&D and a dedicated player of Advanced D&D, ( (I have played the newer versions and was not impressed), I would like to say that it would be really nice if they could just go back to the basics, but keep all of the new races, (with modification, of course).
What I mean to say is, the game has gotten totally to technical and to much is given away freely now.
Not everyone should have magic and/or magic like abilities, and it is more fun to actually have to earn what you get than it is to be given everything. Half of the joy of playing, (and I've been playing since 1981) is in the buliding of one's character.
Also, there are too many perameters involved in today's character sheets. In some games I have know it to take several gaming sessions to get all new player/characters built for a new campaign, especially if it is a large group playing.
To much info is required on character sheets that are rarely if ever is actually used except in the actual building of the initial player/character sheet.
On that same note, referance materials need to remain in book form, simplified, and standard, (DM's Guide, Player's Handbook, Monster Manual, ect....), to many new players are overwhelmed by the amount of info initally thrown at them and become disenfranchized and no longer wish to play.
Get back to the "Meat and Potatoes" of the game and that is the Campaign/Adventure!
