In Tutorial maps the situation is even worse, 25 or more players quit in just less than 10 in game days, only the expeirienced players stay behind, most players don't have the point of staying active. I tried in a South East Asia map that to day 20 I was the only player left which all the other 1 players had gone AI.
I can see how new players have issues with the game:
a) it's very slow; which is by design and I like as I have RL
b) the tutorial on game mechanics is very short
c) building options are very limited - what about roads instead of railways so you have a more gradual upgrade curve
d) moral is very hurting game play right now
e) unit recovery is almost non exist
f) capturing provinces now does not seem to brig any improvements as buildings disappear (destroyed?) and that makes the game even slower
g) unit production is also too slow to make the game engaging
h) naval warfare makes no sense as implemented
My opinion is that the games needs to have more in-between achievements so people stick around. The game needs a bit for Heart of Iron IMHO.
(a) It's faster than Supremacy 1914, so I don't see how that could be an issue.
(b) Yes, but they have made the manual highly visible, unlike in S1914 where it is virtually invisible and where clearly the majority of noobs never see it, so again, I don't see that as an issue.
(c) The building options are actually wider than in S1914 I believe, so again, not a problem IMO.
(d) I really like the new morale system - a lot. The fact that units don't just get killed with one shot, but have to be worn down, gives the game a much more realistic flavour. The retreat and reconstitute was a big surprise for me, and I'm sure for many others, but on reflection I think it's a nice touch that again adds more realism to the game.
(e) I haven't had much experience there, I don't know what unit recovery is like, but given that even depleted units are still reasonably effective I don't have an issue with it.
(f) Yes, the almost total wipeout of infrastructure when you capture a new province is a big disappointment. I'm still not sure though, if this is a bug or a feature, but I hope they fix it.
(g) Unit production seems very fast to me! But perhaps the build queues could be made available to all players, not just High Command users, because if you don't have HC and you're not coming back to this game every hour or two, you ain't gonna build much of an army.
(h) Yes, I think dreadnoughts are hugely overpowered right now, especially with the lack of effective counters except other naval units. Artillery units have an attack of only 3 against them v the dreadnought's 5 and that is absurd, the dreadnought's attack against arty should be reduced to even things out there (after all, arty v arty only have an attack of one). I would also like to see bombers given a higher attack factor against naval units, they are pretty much useless against them now.
And oh, the fact that cruisers have no ranged attack is ridiculous, why couldn't they be given the same range as field guns?
Also, I'm bemused by the fact that submarines, which are supposed to be "stealth" units, can actually be seen like any other units, at least in my experience. How does that make any sense? You might as well just build torpedo boats, they are just as powerful but faster in speed and faster to build.
BTW, one other minor issue with the naval game - the unit icons all look so similar it's almost impossible to tell them apart, except for the subs. Even the harbour looks like another naval unit. They really need to do more to differentiate the appearance of naval units IMO.
