they way Witcher works is it gives you things to do, like Quests (NEW quests, not the same ones, just reversed) and it also has thing called OPEN world that lets you EXPLORE whatever the fcuk you want while rewards you for doing so, plust it has quite some story on top of all this one the other hand, Destiny, while being a VERY good FPS, one of the best ones on the market, well, Destiny gets you 'hooked' as it is without a doubt addictive as sh!t, and once you're hooked, the devs don't have to bother anymore, since you will willingly replay the same mission over and over for hours, weeks, hell even months on end ...not saying one is better than the other, especially because the games are very different to start with, but if one thing is clear, it is that you can easily tell which one of them was made with NOTHING BUT MONEY in mind, and which one ACTUALLY CARES ABOUT THE PLAYER
