Miss the good old days when one purchase you got a full done game.... Guess I'm just an old geezer now expecting that...
Remember Duke Nukem Forever? Star Craft 2? Half Life 3 ("three"!)?
In the old days you did wait for the developers to create the came. I was released years after the first teaser. And if you had bad luck, the developers decided that there was no more marked for it or canceled it to do something "better".
If you want it like in the old days: Simply take the betas as "insider-versions" and ignore them. Wait 2 or 4 or X years and then buy the the whole A Whife And Mother for 3 or 5 bucks.
Yeah, I also want it completed now and here, but no, this is not gonna happen, so I have to cope with that and play something else in the mean time.
