Is FM 2013 actually worth buying?

Because I'm considering it.

What are people's thoughts?

Hard to say, apart from the technical issues I've had I can't say that I regret buying it.

It's a bigger change between FM12 and 13 than there usually is, the question is whether you'd make any use of the improved online/network play or FMC. Otherwise it is pretty much just the little tweaks and additions like always.

I think with the amount of changes in you may aswell, expecting even more to change for FM14 so you'd essentially have more to catch up on.

Apart from that, I'm enjoying it anyways despite limited play time in recent months

if you're happy with 12 stick with it, i persist with it, however it rapes a lot of CPU compared to 2011 which was the last one i had before 13. i can't play it for more than 3-4 hours then it gets really sluggish and slow. if you have a fast PC/laptop though you should be fine. also the in match engine is a bit retarded at times.

Yes, it is. It has its issues, but the improvements makes the game flow even better. Training system was a great improvement, and it still fun like all previous FM editions.
