Since Sponge is built on top of forge, does that mean the developers could make a mod/plugin loader that builds on Forge and allows the client to have multiplayer plugins on singleplayer?
Yes, you will be able to have multiplayer plugins on single player.
Now you can rollback what your drunk self did last night!
Finally!! Now all we need is someone to port WorldEdit and mcMMO and life = complete.
Like @sk89q already said. You are able to have multiplayer plugins on singeplayer. Which ofcourse makes this much more powerfull than Bukkit.
WorldEdit is already Forge compatible. Doesn’t need to be ported.
