Sumo will take alot of time until we see anything of it. The main issue is, that our current game version an older code structure uses which is not compatible with the code that is needed to support the sumo gamemode. In order to support the sumo gamemode code, it is necessary to modify/change/rewrite etc. the existing code to support sumo and other newer gamemodes. But since this takes ALOT of time and will not happen that soon, because there are many other (higher) priorities and only a limited amount of time to work on these.
I already heard that players need vpn to play Project Torque, but its more or less the first time, that its someone from russia who reports this. People from brazil are usally the ones who report to have connection issues when not using vpn.
We dont know why some players need vpn to connect, but we hope to find a solution in the future.
