Running on fibre is like playing this game in dream mode since you don't have to worry too much about lag and server lag issues, but as far as I can remember it was a mission to play since they didn't have servers in the UK and if they did they used to be over pop almost 24/7. No clue how it all works now since I just haven't been able to log in and starting the painful grind back to where I was when I left the game 4 years back.
Is it worth playing and spending the time, Yes it is, there's still quite a few people that support it still through the changes and challenges it has gone through but it still remains very competitive and there are quite a few clans out in it that take it really seriously. Worth getting it since it is free after all, but be warned there are lists of things that are wrong with it, would love to list them all but haven't got the time. (Balancing of units and very biased towards particular nations)
I would have game-play but like I said still battling to get back into the game even though I have a (press pass). Heroes & Generals gets a 6/10 on the LoG chart, its been around for a bit and still needs loads of development with little to no support. Still playable, should've been completed years ago.
