I don't know, every now and then I see people arguing over usefullness of Victory Towers, so...
more useful than watchfires but not so useful as to *try* to include any - they are still a wasted square.
Really, 61 medals in PE would be great, but 610 is just insane. But, maybe, that's a feature for those, who don't want to push their Arcs, because that's not cool anymore or something like that... I haven't figure that out yet.
It does seem quite high for a 1 hr production. I'm just saying using other medal producing buildings as your guide is hardly a good frame of reference given that they're all not worth using for that purpose as it stands. That said, 61 would still be miles ahead of other medal productions from buildings and might be good enough to be worth using for a change.
Frame of reference : A sunken treasure including half road nominally takes 7 squares. it needs some population too so we'll just round it off as 2 sunken treasures eating up a whole expansion. If you're in fact using it to get new expansions how long do you have to run it to replace the space the building itself is using? (at 610 an hour * 2)
When your next expansion is:
30000 : 25 hours
40000 : 33 hours
50000 : 41 hours
65000 : 54 hours
85000 : 70 hours
105000 : 86 hours
...
660000 : 541 hours
I can agree to be going through those midrange expansions so fast seems extremely powerful as is.
I can also agree that 10 times those lengths may still be useful (61 per hour instead).
But I'd further point out if it's to be brought in line with other buildings it's more likely to be around 10 per hour (half a terrace farm 4 hr production, scaled down by 2.5x to get a 1hr value instead of a 4hr value) - and that'd just be a flat out waste of space / production time.
No, there is no limit to medal expansions
All you need is love... ekhem, medals
Of course there's a limit on medal expansions - currently the 660k one is the last.
