Like many things in life, for me, the hardest, most complex roguelikes are the ones that give me the most satisfaction. The things that take the longest to get into, that take the longest to learn, they're the ones that reward you the most.
That's how I work, at least! I guess what I mean is - go ahead and play those roguelikes, but do give one of the more complex ones a serious go. It might just be worth it for you!
