That would be great, but normal tf2 gameplay isn’t commonplace in community servers, the closest equivalent to casual is probably uncletopia, and that has plenty of changes to be a bit more competitive like class limits. most servers are just 24h ctf or gimmicky maps with rtd, if you want to play the other modes like payload in a vanilla enviroment, casual is the only major provider of that.

Isn’t the mega drive just the genesis, I understand counting the add ons for the genesis, but the mega drive?

Any other custom roms that do have support are also welcome.
