1. Trophy presentations and celebrations. Have you ever won a major competition, like the Champions League and then thought "Is that it?". I think that this would be on most peoples' lists.
2. A bit more personality in press conferences. The same responses over and over are just boring. It looks as though some responses are tagged as arrogant, or supportive of players, etc. so that could be kept - but it would be nice to have in-line editor to customise the content. So, for example, instead of saying "I really do think I am the special one", you could say "I am a god. There is no one who can compare to me. What other managers can do with a team of superstars, I can do with an orange". Quirky stuff like that.
3. Continuing the theme of injecting some personality into the game, the message inbox could do with an upgrade. All the press stories and off-field events are pretty cookie-cutter stuff. It's no fun having Mario Balotelli in the team if he doesn't occasionally do something absolutely crazy. Likewise, when you're managing Rangers, you should get the Celtic manager coming out with outlandish conspiracy theories. And where are the newspaper stories of pampered premiership players crashing cars and raping people?
4. More options for club facilities. Currently, there's no equivalent of Barcelona's La Masia or Milan's Lab. That should be a lot more involved and complicated than simply asking the board for extra junior coaching or increased recruitment. It should be more in-depth.
5. Following on from the above point, I'd love to see inclusion of younger youth set-ups - under-17s, under-15s, etc. and scouting, coaching and matches to go with it.
6. You should be able to have different tactical instructions for when your team has possession from when they don't and the team automatically adjusts.
7. The match engine still needs tweaking. Something I've noticed is that AI teams have incredible accuracy with both headers and 'keeper clearances. The latter especially - opposition keepers almost always do long clearances with pin-point accuracy to a team-mate way up the field, whilst my 5-star keeper can boot the ball to an opposition player with relative frequency - he doesn't mess up often, but a lot more often the opposition keepers do.
8. I've played FM 2012 and 2013 an awful lot and I've never seen a club go into administration, let alone liquidation. I even once used FMRTE to really start messing with a chosen club's finances as a test - but the club always secured their finances, either with bank loans or the debt was mysteriously cleared in the close season (with no sugar daddy). A case in point: I created a data file that started Rangers and Celtic in the Blue Square Bet Premier. I really messed with Celtic in FMRTE to see if I could make them go bust, but their debt kept mysteriously vanishing. I used the Destroy Team feature to make them lose games in order to keep them in the lower divisions to see how that would affect their finances. Four seasons in and Celtic are in the nPower League Two, paying Joe Ledley £53K per week.
