I used to play a lot of Tower Defense, and I have been getting back into it since the update, I stopped due to a mix of just straight bordum in Tower Defense, and in Minecraft in general in 2020, but I have been getting back into it and its fun, and as others said, TD is a very interesting game mode, that a lot of other networks doesnt have. I enjoy the strategy aspect behind it, with the slight micro managing (more so when it suddenly becomes an everyone V me)
Im hopeful for TD, it might of had a low, but with the new update, hopefully the numbers start climbing again
