I've seen a good number of posts against the release of big box board expansion after Innsmouth is put out. The main reason seems to be that there's not enough space to play with 5 boards and it becomes impractical. Another issue I've seen is card stack dilution, although that argument could used for any expansion, not just board expansions.
But if a board expansion is released, do you feel so compelled to use it with all other available boards that you'd rather not have it at all than simply leave a board out, or just use the base board and the new board alone?
I'm in the camp that would rather there continue to be board expansions, even if I can't use them all at once. I think I would tire quickly of having only card expansions coming out. Where do you sit on this issue?
