No. There's a lot of Mack tiles - a lot more than there are RTP. I think about 20 or more tilesets? About 6 towns (2 versions of some), 3-6 inners for each town set, 3 or so forests, 2-3 wilderness roads, ruins, castles, towers, maze and a lot of extras... yeah, there's a looooot of Mack tiles.
The sprites, though, well, the proper Mack sprites; yes, there's not as many as there are RTP, but he also released a big bunch of RTP-styled sprites, so...
