We played this game for the first time and we were with the three of us. All having one samurai in the field to make it less confusing.
The Japanese garden I made was of perfect size. With small stones we denoted the different zones of the RSBS arena. We chose to make a simple samurai based on the two sworded gladiator. Now all samurais were quite similar only difference in weapon being 2 swords or a 2-handed sword. Furthermore the difference was in the dice rolls and division of attribute points of course. This was for us enough for now since we were learning the rules of the game as well.
I think it worked out well actually. It took us 2 hours to play this version the first time including making the samurai rosters. No campaign just a simple fight to the death. Good for the first time.
I think we will be creating our own samurai rosters and the major change in the rules being the fighting styles. We just have to create some fighting styles for samurai and the game is as good as converted. Campaigns can be played just the same not having gladiator schools but samurai families/schools and we're off! Next games will be play testing our own created samurai fighting styles which of course will be posted here.
Good fun this new game and when more familiar with rules can be a quick game to start or finish a gaming evening!
