I think that I fall into the second group of people. I somewhat do, anyway. I always fall into the same trap: "oh that game looks good, let me try it!" and then I am so far into the grind before I even realize what I've done! At that point, I feel bad "giving up" even if it becomes tedious. I eventually do give up, although another game usually fills its space. I am lucky that I am able to stop myself short of buying anything with real money, because I am sure so many people can't resist buying the tools that ease the grind!
