I have two games – one mode-based and one score-based – and I enjoy the variety between the two. I like it best when the modes drive you through a story, but I can't stand when there's no randomization. For example, in The Sopranos, you have to do certain tasks in the same order every time to progress and that gets dull. But I enjoy games like POTC and MB, where you can pretty much choose your goals and TOTAN, which mixes up them up and sometimes lets you skip them altogether.
