Another vote here for skyrim, I brought into the hype and got it on my PC ages ago. But I just never fully got into it, and never went back to it. Probably due to it taking ages to get anywhere.
However having said that, I am debating giving it another shot on the PS4 when the HD one come out. Because i LOVE the idea of open world and dragons, and I really want to like it.
Fallout is a similar story for me, I had fallout 3, never got on with it and really disliked it. However, again gave it another shot with Fallout 4, and I did actually get on with it a lot more and quite enjoyed it, however I never found myself going to play it or being drawn to play it.
Ill also throw another game into the fray, The latest Star Wars Battlefront.
Now, despite the gameplay and graphics being amazing, 10 mins into it, you've seen everything the game has to offer and your left feeling "is that it?" However, its a game I could probably pick up now and again when I have a spare 30mins or whatever to play and I need a game thats quick to play (FIFA used to fill this gap for me)
On the complete flip side of this whole post. A Game i picked up assuming that I would not get on with and hate, when in actual fact the opposite happened and I fell inlove with was, Dark Souls. Didnt even pay for it either as I got it with games for gold, I only tried as i was tempted by Dark Souls 3. I have 30 odd hours notched up on it so far, I haven't played for a while though as had other new games to play. Once I finish the first souls, ill be picking up the third one, Will probably be like a fiver by that point as it will take me ages to find time to finish it
OP, you should turn the post into a Poll!
