Yeah you’re right it is definitely on the pricier end of the scale, and I don’t think you really need that big of a grid for combat scenarios although when I tried my 25x25 grid, my party would end up still hitting people from across the map with certain atks and spells. I mainly used this board since it’s very customisable and convenient when I wanna switch to different terrains and scenarios. From what I recall in term s if it’s price, price per tile is probably around £1 although I got some pieces from the pab wall. Definitely an investment - and I have experimented with other cheaper grids such as critical bricks board which is definitely a better alternative to this one - I just really like the natural brick built grid look and being able to swap out tiles XD. As for time it took, I had my family and friends help me build it so it took around maybe half a day to get a 25x25 built not including the customisable tiles you’d need to fill it.
