Lol, I guess that's what we do in real life too, consume every resources we can lay our hands on as soon as they spawn. I think new products these days don't face these type of problems though, user behavior doesn't pose a problem to in-game ecology anymore, rather gamification is used to take advantage of human nature and modify user behavior. The last multi-player game I tried was mobile (Last day on earth) and I doubt they had this type of problem but then that's because lately devs have learnt that UI must adapt to UX and design must always take user behavior into consideration to be successful.
