In SMBX 1.3, I had an option in the editor to play online, you could create one server, you could join another's. But that feature was incomplete, and as smbx was discontinued, they never finished it. But PGE and SMBX 38a are quite active, so they could add an online mode to the PGE engine, but of better quality than the old SMBX, it could be very entertaining for everyone, since online games are always well received by the people. I knew that the PGE editor had an online feature (I may be wrong), but if the engine has it ... It would be the best.
