This does remind me of my favourite game of FM, where I put myself into the game with good attributes, potential 130 or so, and let the game play for 10 years to see where I'd end up. Was playing for Championship level Aston Villa, who'd just got relegated despite having a European Footballer of the Year in their team. I remember selling him on for £25m or so and throwing a new defence into the team, and I had some all star Andorran defender that was the linchpin of the club. Most cheerful moment was recruiting myself and finding out I was a damned good defensive coach. And some regen Belgian wunderkind whose name I can't remember but it was slightly offensive sounding.
Anyway, now I'm looking into messing around with the database some more. I'm going to check the technicalities of it, but see if I can form some kind of national team in club team format. I tried something like this in the Danish league but the players would transfer between clubs, sullying everything. Apparently the Malaysian league doesn't allow anyone from outside their nation to play in their league. This might be the best way to fix something up.
