how do you make a TNT Wars server?

Use something like MCGalaxy. Currently I can't think of any other server software that also offers TNT Wars. You could also try making one yourself.

There are no pre-made tnt wars servers for classicube. You would have to program the scripting/code for the plugins. Also for something like that, you would need a different server host other than mcgalaxy. 
you would also need to have a strong computer, since “vanilla” TNT exploding in mass amounts can be stressful for a low quality server and/or processing unit.

my advice, don’t use a chrome book to host it, and go for it. TNT wars is a fun game and I’d love to see it in classicube!
