I grew up with BECM. By the time this Cyclopedia came out all my friends were hyped for AD&D Second Edition. So I never got to use this back in the day.
Nowadays I play solo old school DnD. I got tired of using my ipad and printing out rules to remember. So I ordered this softcover and can reference what I need quicker. It also feels more real than digital stuff.
The printjob is OK- the cover wasn't cut perfectly, and there was at least one smudge inside. It's POD, so I evern smeled the ink. However, it was much better than anything I could print at home. And the price is truly amazing considering you get what is ultimately the Ultimate Old School D&D ruleset and Mystara primer.
Even though the designers of 5E are nice and it remains the #1 RPG tabletop game, there is no question that 5E has overpowered "builds" and values combat and skill checks instead of the intended experience.
PS: I made some (not all) suggested fixes using this: https://www.acaeum.com/library/cyclopedia_errata.pdf
If you want to use the old school rules, you might as well make sure they are free from minor errors.
