Some games just feel better on a console, to me anyways. I'd rather buy a console and a few games that I actually play, rather than spend three times that for a computer and a whole bunch of games I never play but bought because they were on sale and I thought I might play them eventually. I play games both on a console and a computer, and I find some games work best on a console and some work better on a pc. So I'll always have both of the major consoles and a computer, and I'm quite happy with that arrangement.
I'm just waiting for bugs to get worked out before I pick up the new Xbox and the ps4.
