Cool. Don't find many people making a board game unless you go to specific communities for it (ie board game development subreddits etc). You see people making video games but you don't often run into individuals making board games. It obviously happens because there's a lot of indie board games rather than them all being made by only big companies, but I haven't come across it much outside of specific communities.

What sort of board game are you making? Are you thinking of releasing it commercially?

Also, yes keeping stuff in balance can be a tricky part of things. Mine originally started as story only (sort of somewhere between a choose your own adventure book / telltale game etc and an RPG like dungeons and dragons) and I had to work out how to make NPCs right in terms of difficulty and player strengths (made harder by character's levelling and NPCs being at least partially random by a lot of them being cards you draw) but there wasn't too much balancing concerns. Then I saw the potential for PVP as well though and that made me have to consider balance a little bit more too so one player isn't OP and doesn't just dominate the game.

I hope your game is successful too.
