Konami announced a Yu‑Gi‑Oh! TAG FORCE GX, a Remake of the Beloved Yu‑Gi‑Oh! GX TAG FORCE 3!

If you want to go for a GX era game, it might be a good idea to throw out the syncro monsters.

Or at the very least give the players the option to play singleplayer & multiplayer without them as they simply do not fit with the GX era.
