Now that WotC is releasing (in stages, apparently) it's TSR era material in PDF over at DnDClassics, the question of access to earlier editions will slowly be lifted.
The question will than become - play with the original rules or use the retroclones or both?
My current AD&D 1e campaign uses the core AD&D 1e books and OSRIC pretty interchangeably, with my own house rules on top.
I like the retroclones because they are much easier to read than the originals, which makes them an easier book to reference during play. But I like the originals because I grew up on them.
So, what about you? Originals or retros?
