DCC is basically a mix between AD&D 1st or 2nd edition, with an alternate complex set of rules instead of the common ones. It tries to shoehorn in the abilities and feats of 3.5 but in a way that makes those abilities more flexible and descriptive. It is still a super restrictive ruleset because you can't just tell the DM what you want to do, you still have to have an ability that letshe you perform that action. Also magic is super crazy and randomized all the way down to the spell effect and how it performs a particular task. For example I had a spell to summon food and the effect was that it turned objects into food items; I used it to turn a giant evil expensive looking statue into cookies. Effectiveness of the spell is also randomized so it's never really at the power or effect that you want. I found that it can be fun for a one off adventure, but I never can get attached to my characters or vested into a game because it is too random. Roll20 has other d&d basic games going, which should be similar. Swords and Wizardry is probably the closest ruleset to this.
