The handheld one is good on the go, but its pretty crap compared to the actual game which is much more in depth.
Id compare FMH to the Classic mode on FM14 myself.
With FM14, i sped the game up a couple of years and Brighton were bottom of League 1 after 13 games, took them over and 10 games later were up to 10th, 3 points off the play offs with 2 games in hand. Have a tiny squad too but signed a few players on free transfers to add experience and numbers.
My VidarFK save got corrupted one game before the final game of the season; a win would have won us the Premier Division title. Now I'll never know. Actually had to take a month or two off the game after that, really pissed me off!
Back now though with the Albion. Flew through the Championship with some good signings. Sitting 11th in the PL now. Team at the moment:
GK -Wiesse
LB - Casado
CB - Caulker
CB - Dunk
RB - Oduro
RM - Buckley
CM - Thorne
CM - Stephens
LM - March
ST - Sobiech
ST - Vydra
Got some young blood in on frees as well, they'll be making forays into the 1st team once I'm secure from relegation.
