Maybe someone has an answer for Pixel intension .......
the 2,3 and 4 slot trains have higher profits than 2x, 3x or 4x regular 1-slot trains.
Players playing longer times have often bought electric trains for GEM and in most cases the waggons for gold.
Lets say I bough 10 power 100 trains for GEM as a set. I need 10 IT-slots to let them run. Each train brings 180 Mill gold = 1.8 B gold.
Now I buy a 4slot and a 2slot set-train for gems. I invest 1400 GEMs for the locos.
The U-train brings 400 Mill and the S-train brings 900 Mill. So I have now 4x180 Mill + 400 Mill + 900 Mill 2.1 B.
So I make more profit than before.
But I also must sent 6 trains to depot or storage, because I have no slots for tghem to run.
This makes 6x100 waggons + 6x1 locos, 606 items more in storage.
I think nobody playing long time has so much storage left - and the policy of pixel is, maybe all 5-7 weeks a SO/VO of 200 storage-items for GEM.
So, the policy of Pixel must be:
a) people in future buy only waggons for GEM and not for gold (because they don't in most cases need no storage-unit)
- or -
b) players delete the waggons and destroy their sets bought with GEMs.
For me - I am always short of storage, actual I have all slots filled (local, IT, depot) and only 114 left in storage.
I'll never delete waggons of trains I bought for GEMs, so for me: if there comes not more storage, I can't buy new trains - no matter they have 1,2,3,4 or 10 slots.
How do you solve these problems ???
