I work in real estate and my job pays way too much to entertain any thoughts of creating an own game anymore.
I made an offer to buy this game like 4-5 years ago, never received an answer. We were around 35k users back then. Also had some loose contact to a polish manager who claimed to have a working engine, but had no interest of developing it further. Can't say I did not try to do something.
I have never said anything on a possible ROI, however the cost of getting an app done are really not that high. If you are willing to pay for it. Obviously the owners don't want to. For whatever reasons.
If the devs would have spent half the time I wasted writing on coding some of my suggestions I would have very much appreciated it. Instead they chose to tweak stuff.
