There is a tendency in the OSR to muck things up, add too much bloat to the game, and put in so many new ideas that we lose the brilliance of the original game. Part of the reason I loved Old School Essentials Classic Fantasy was the beautiful simplicity; there are not many ways to go wrong with buttered toast, and OSE Classic was the perfect, simple, atomic, perfect recreation of the original game.
OSRIC 3.0 is exactly like that, but for AD&D.
Where Adventures Dark & Deep goes off the deep end of the pool with hundreds of pages of new additions ot the game, the ideas feel muddled and overly complex, where if all I wanted was an AD&D 1E clone, then I do not need all that extra fluff and positing of what could be.
There are times I want only the base game.
I want simple.
I want the best options.
I want a clean and streamlined game.
If I want to play just like it was the 1980s again, OSRIC 3.0 is the perfect game. The PDFs are PWYW, and you can get a free option if you're just checking them out for curiosity.
There is a post on Dragonsfoot that compares AD&D and OSRIC 3.0, and many of the differences stem from carefully considered legal reasons. The differences are extremely minor and not really a game-changer, and are only for rules lawyers. Some are welcome simplifications and clarifications (one roll to pick pockets, and rules for high-STR characters wielding 2H weapons with one hand). I like the changes and improvements, and this version is far clearer written than the original AD&D 1E PHB and DMG.
If I were starting new players with 1E, I would be playing OSRIC 3.0. Never has there been a clearer, easier-to-learn, and well-represented version of the game than this. This is a cleaner-presented, product-improved 1E with all the best options and mechanics.
And the game is derived from the Creative Commons release under a new, more open license. The now-hated OGL is finally gone from OSRIC! The game is free to live its own life without legal threats.
Stepping up from a BX set of rules to full 1E is a refreshing experience. A lot of what was left vague for younger audiences is cleared up in the full 1E version of the rules, and there is less room for interpretation in critical areas. OSRIC 3.0 seems easier than OSE in a few ways, with clearer rules for things that will come up during the game, and there will be less "winging it" at the table and more straightforward play and adventure.
Gary Gygax wrote AD&D for organized and tournament play, and the rules were designed to address the most common questions and situations that arose during play. While BX is perfectly playable at conventions and public settings, 1E clarifies many things individual groups would have to "make up on the fly" or "wing it," and standardizes play, keeping organized play clearer, fairer, and more consistent across game masters.
If you are playing organized play, 1E is a far better choice since less is left up to interpretation. Everything is compatible, from BX to games like Swords & Wizardry, so if you want adventures or more character options, they are there for the picking. The OSE Drow race? Use them as-is. The bard from Swords & Wizardry? Use that as-is. It all works together nicely.
But basing your game on OSRIC gives you a simple, consistent, and clean start. This is something more advanced, expanded games can't deliver, since you tend to have to "take in everything at once," and you lose that beautiful simplicity I like to see in a game.
