I still play custom edition all the time! I find it so fun, especially the custom campaigns where u can play as the flood. The multiplayer I great too, and from what I've seen about 100 people are on maximum at a time, and it's still good with the custom vehicles and stuff. Although many people don't have it, you should get it if you can. Why didn't the ever make a halo 2 custom edition, though, I wonder?
