FH2 is all I ever play on my XB1, I feel it's kind of a waste having the console, I also have a year of EA Access so I got BF4, FIFA 14, Madden 25 and PvZ and FIFA 14 is the one I play occasionally (got it on PS4 as well and play it there more often). Never been a fan of Halo series, so I'm not sure if I'll bother with MCC.
I generally agree that it's a waste to buy a console for one game. However, given that you can only play one game at a time, does it matter which one you're playing, as long as you enjoy it? I mean, if you're enjoying FH2 while you play it, then I guess the console is doing what it's supposed to, right? As long as something else of interest is out by the time you finish/tire of that game, I think you're doing just fine.
already pre ordered GTA5 and PES 2015 for PS4.
