I would Go with Option A. That way its one click to open and then you decide to do whatever in the options that are offered. Would make the Game little better and give you the option to think before you just click and move.
I think you missed the point.What they are going to build with the split lab is that you can build out the lab in a way that suits your playing style.
At current settings your lab will fill up in 12-16 hours depending on if reseacher is active or not.
You will have two options
option 1 if you are a player that logs in 3-4 times a day you do not need a high storage limit for Research points (RP) because every time you login you use your points on research. so you choose go for a bit faster in generating RP but at the risk of losing out points if your storage capacity is too small when you miss a login session.
option 2. You are an easy going player that logs in maybe 1 or 2 times a day max, so on most days your lab will be full after 14 hours on average so you currently you miss the points generated after 12-16 hours. With the new lab option you can expand your lab to a level to store points generated over a 24 hour period meaning you wont lose any points and even as a low activity player you can still research the best trains because you can store more points and don't lose points anymore because the lab storage is full.
I did not missed the point; what i say is that such a upgrade, in my eye's, will ruin this game.the fact that you have nou 60 lab levels instead of 25 isnt making the game easier. also i think this isnt the solution to make the game better
I dont think we can make a decision if we dont know the stats you plan to give these buildings.
I'm for the option you can choose between speed up the time of generation research points and/or upgrade the storage so you can upgrade the lab to your daily activity.
Give both options 25 levels, split the prices and the build time for each upgrade so the total time and money to spend stays the same.
And the possibilty to upgrade simultaniously.
