Mr Cholewa described toy soldiers battles as "essentially a tactical game".
In layman's terms he described each army as having particular strengths and weaknesses and each soldier or cavalry having different capabilities in battle.
"Like a more complex game of Risk."
Mr Cholewa said he got into toy soldiers war games about 35 years ago.
He started buying toy soldiers as a child but eventually moved on to reading books by toy soldier pioneers Peter Young and Donald Featherston about how to actually recreate battles with games.
Sixteen gamers from Palmerston North, Dannevirke, Wairarapa, the Hutt Valley and Wellington brought their armies for the day.
Saturday's game was a friendly but Mr Cholewa is looking to host a full competition over two Saturdays in the future, with dates to be decided.
