Currently playing Fifa 14 and GTAV.
Fifa is basically the same as its predecessor, just some new gameplay mechanics and features. However, I'm not fond of how slow the gameplay has suddenly become... I get that EA wants to make a more realistic experience but essentially you're harming the experience by doing so. Players feel extremely slow and can't dribble, passes and movements should feel more fluent - they should look at PES (rival) for inspiration there. So far I'm not that impressed and I'll probably go back to Fifa 13.
GTA V is great of course, and the online came out a few days back. I had a few problems but nothing major, seems like everything is smooth now, good job Rockstar. Online is hella fun though I just wish I had more time to play it =(
