Explenation;
We all know of the Napoleonic war, it stretched over multiple continents (like a World War), most of the participants of WW1 were in it (Excluding Ottomen), new technologies were tested during the war (rockets).
Only difference is that, unlike the other World Wars Germany wasn't the juggernaut starting it.
---------------------
CONCLUSION -------------------------------------------
From now on we should refer to WW1 as WW2, WW2 as WW3 and the Napoleonic War as WW1.
