I feel like this is such a key element that so many FM players don’t consider when it comes to intakes.
Judgement on an intake almost always comes down to how it will impact the Users first team.
Honestly, the time required is not surprising. Sometimes this kind of thing is a little too much of a niche compared to what FM can realistically achieve. The fun though, can be found in the process of trying to replicate rather than actually achieving the end result. Either way, I look forward to seeing what you come up with.
