No better time than this year to do so. All Aboard Games are putting up pre-orders for later this year- with 18Mex probably being the most newbie friendly. Grand Trunk Games has just done 1861/1867 on KS, which has been combined also in a nice approachable new packaging. They will be doing 1889 later this year which is wildly regarded as the 18XX game for newbies- it's also a really fucking good game and is now within my Top 3 games of all time.
Tet will be along shortly to do his pitch for 1889 as well. :p
