Ice skates

[Walrus143]

You should add ice skates to the game which could be used to travel quickly on ice, it probably wouldn't be that useful but it could be a fun thing to add to the game.

Were skates used during that time period?

Apparently!

Here's a discussion of some folks making skates from cow bones and trying them out:

Then it seems like a very nice addition, in particular since it's especially useful in Finland. The problem, though, is that it gets rather tedious to switch between skis and skates as you get on and off the ice, although dual using a ski pole as a skate pole (perhaps by turning it upside down, where you'd have a metal point) would help. It probably wouldn't be particularly useful for hunting, as the time needed for switching would allow the prey to get away, but it would be useful for travel, especially if it's a little bit faster (and less tiring) than skiing.
