When I mention WW2 here , I really mean any conflict say post 1930 and any scale. Compared to other eras such as Ancients ,Naps etc, I personally find this an expensive era for starting up wargaming whether it be FOW , KGN or any other ruleset you could care to mention.
The culprits here must be vehicles . I know you could argue you don't have to use vehicles in WW2 and that is true, but lets be honest the main attractions for WW2 are vehicles and tanks at that.Once you buy one tank you will want to buy another. I appreciate great strides are being made by the likes of PSC who are constantly expanding their ranges in various scales with reasonably good quality plastic vehicles and figures at reasonable prices. You can also argue that has already happened in other eras eg in Naps . Both Perry's, Victrix and not forgetting Warlord have introduced top quality plastics which have lowered the cost of starting up in Naps. Beautiful Napoleonic armies are now achievable at fraction of the cost.
Which begs the question why in most poles is WW2 the most popular choice ?
Is money no object ?
Food for thought..........
