Replayability - some games lack it completely, but there are others which just thrive in the area. Whilst we've all probably played dozens of titles which we have absolutely no inclination to return to after completion (or maybe even before completion), there are others which we find ourselves wanting to revisit regularly and repeatedly.
I'm just wondering what games, for you personally, fit this description. What games have you played which possess the greatest level of replayability?
Now, this doesn't necessarily mean the games with the greatest exploration, the games with the most freedom, or the games with the largest number of different routes to take and alternate decisions to make (though those can certainly be factors in creating enhanced replayability, for sure; I'm not discounting that), but it simply refers to games that hold elements which you just constantly find yourself wanting to re-experience.
So go ahead and share these titles with us, and also tell us the reasons why these games are so replayable for you.
Also, alternatively, feel free to share the titles of the games which you found to have the least amount of replayable value; that could also be interesting.
