What do you guys use to represent PCs, NPCs, vehicles, etc on the table? My group was thinking of trying to find matching minis for each PC, but for now we are going with classic non-descript board game pawns in a different color for each character, which small (1cm) colored blocks to represent NPCs. I'm drawing maps and ships, vehicles, etc on paper and cutting them out when needed/helpful.
What does everyone else do? Does anyone go all-in getting minis for PCs, ships, etc? Do some people not use maps or visual representations at all?
