Really good thread. I'll be interested to see how you perform in the league.
It's been a while since I've been on here as I generally spend ages on a version of FM working towards a single tactic that I don't have to tweak at all, so have only just moved on from FM14. I'm having a bit of a struggle with playing away in this version so far, so will be interested to see if the simple approach continues to work for you as I'm very similar to yourself in that I'm determined to find a nice simple, balanced tactic that can be used over many games and allow you to be successful by simply improving your squad. I've managed it on every version I've played so far and hope FM16 will be the same.
In contrast to you I've started with Barcelona, as I always tend to start with a big team and have some fun before moving onto a long term game with a minnow (usually Darlington or Gateshead with a Sunderland save in between). So far results have been mixed, but I've been getting a bit carried away with both the team and player instructions due to trying to get the best out of ridiculous players such as Messi and Naymar. At one point was 7th in the league and almost got sacked.
Anyway, gone off on a bit of a tangent there. I really like the style of this thread and look forward to see how it goes. I'm tempted to go into my second season with Barcelona doing something similar and seeing how it goes.
