Exactly. A retroclone is about restating the ruleset, usually in a clearer or more concise way.To me, a retroclone is defined by copying the rules of an older game as closely as possible. Like Old-School Essentials.
There are plenty of great games out there that copy the feel of the old-school games, but they're not retroclones. Like Shadowdark.
The OSR scene is about recreating the feel of old-school games. It is inclusive of retroclones.
