CTWC is yearly, and is neat, but most of the community and talent is developed at the monthy tournaments called Classic Tetris Monthly. The guy in charge, Vandweller, doesn't get nearly the credit he deserves for fostering the communtiy. If you're curious, here is the twitch. https://m.twitch.tv/monthlytetris They also upload to YouTube under the same name.

CTM is where rolling was first demonstrated. Eric getting to glitched colours happened during CTM. They also had a level 49 line cap (now 39) prior to CTWC this year because they had a full 10 months of tournaments showing the necessity for it. CTWC did not heed their experience, unfortunately. Also the past three champions are frequent winners of CTM. Except Joseph, who used to be a big part of the scene, but he's off to try other things.

Anyways, I recommend CTM over CTWC as a starting point if you're reading this and are curious.
