How do I put this...
Pre-4.0 is a better RPG, 4.0 is a better game.
Old editions were full of the balance issues, overpowered obscure builds, and rulebending that make solo-RPGs fun, but are annoying when there're other people involved.
4.0 is balanced, (In old editions, at low levels fighters could hit things well good, casters could cast magic missile once a day. At high levels, fighters could hit things really well, Wizards had a spell called "Wish" that was exactly what it said on the can.), the rules are tighter to prevent abuse, and the focus on the mat and miniatures makes it a more tactical experience.
