For smooth transition and the best experience I'd love to have a new sim every ~5 years, not every year.

Well Cnopi your going to be extremely dissapointed then, as I was told, the new business model and the only way to survive this genre now is to support each game for roughly 6-9 months then develop a sequel. This is exactly what is happening for CoD,

As long as new standalone releases can merge with older ones, so that you have the sum of all contents and lose nothing (like IL-2 did from Forgotten Battles Onwards) that's more than good for me.
