It sounds like you are working on an interesting map for FS25 set in a fictional Northern Irish location. The inclusion of two farm yards, a small holding, a medium-sized yard with working pits, and a shop adds depth to the gameplay experience. The fact that it is a 2x map suggests that players will have a more intimate setting to work within, which can be both challenging and rewarding.
The promise of future updates to expand the map for multiplayer is exciting for players looking to collaborate and work together in the game. With 20 fields planned for the map, there seems to be a good variety of tasks and activities for players to engage with.
It's great to hear that you are actively working on the map and planning to update it as you progress. Keeping the community informed about the development process can generate anticipation and interest in your project. Best of luck with completing the map, and I'm sure the FS25 community will enjoy exploring and experiencing all that your map has to offer!
