Oh, maybe I didn't make my original post clear. I've got all the expansions but I don't play with the big box ones except Innsmouth as I don't like them and only really got them for the extra cards and investigators. I don't like them as I only play solo and find it takes me to long to set up and play with them. I occasionally play Innsmouth as it's my favourite Lovecraft setting. Usually I just add one of the small box expansions.Aha! Well, I'm of the opinion that MH is worth it - and I don't play with multiple expansions. But I'm happy with all the extra cards that I can use. There's definitely additional benefit if you do play multi-expansion as (for instance) the new Mythos cards are designed specifically for that scenario.
